About this file
This is a Sign Plan Overview and Recommendation Report for Minute Man National Historical Park, prepared by the National Park Service Harpers Ferry Center in December 2025.
The report evaluates the existing signage system at the approximately 1,000-acre park, which straddles Route 2A, Lexington Road, Monument Street, Liberty Street, and Barretts Mill Road through Lexington, Lincoln, and Concord, Massachusetts. The park receives approximately one million annual visitors, with peak visitation during April commemorative events and fall foliage season. Field data was gathered November 7-8, 2022, by a four-person team. The primary findings indicate that the current signage system lacks clear wayfinding, contains worn and faded signs with gaps in coverage, lacks labels for historic sites and buildings, and does not comply with current Federal MUTCD standards for regulatory signage (STOP, ONE WAY, DISABLED PARKING). The report identifies specific deficiencies including minimal directional signage along trails, non-compliant accessible parking signage, and missing distance markers on several trail sections (Vernal Pond Loop, Fiske Hill Loop, Parkers Revenge Loop).
The recommendation framework encompasses four signage categories: informational, identification, directional, and regulatory. Key recommendations include implementing Highway Guide Signs, Boundary Signs, and Pathfinder Signs for vehicular wayfinding; establishing covered informational kiosks at parking areas; installing compliant trailhead panels identifying restrictions, difficulty levels, and accessibility status; adding trail distance markers at 1/10 mile increments; updating trail directional signage using upright sign series (12" and 18" options); providing consistent PRIVATE RESIDENCE identification signage; replacing non-compliant regulatory signs to meet MUTCD standards; updating accessible parking signage to comply with ADA requirements and proper height/color specifications; and ensuring ADA-compliant room signage with appropriate Braille and contrast ratios. The project is planned for completion in advance of the 250th anniversary of the American Revolutionary War in 2025.

Introduction
Minute Man National Historical Park is comprised of over 1,000 acres and straddles Route 2A, Lexington
Road, Monument Street, Liberty Street, and Barretts
Mill Road through the towns of Lexington, Lincoln, and Concord. The park has approximately one million visitors annually, with peak visitation during April commemorative events and Fall foliage season. The
Visitor Center(s) are closed during the winter season, necessitating that clear and concise wayfinding is available to provide direction during these off times.
The purpose of this report is to evaluate the current signage system in and around the park, including vehicular and pedestrian circulation guidance. The goal set forth by the NPS is to develop a comprehensive signage replacement program that is easy to follow, reflects the NPS signage standards and allows for expansion and flexibility. The project will be installed in advance of the 250th anniversary of the start of the
American Revolutionary War, in 2025.
The project team gathered field data over two days by a team of four from November 7-8, 2022. This report includes the on-site survey of existing conditions, inventory of the current signage, and voids and gaps in the sign program. The report also includes recommendations for improvements to provide an appropriate sense of arrival, direction, and information designed to improve the comfort level of all Minute
Man National Historical Park visitors.
The current sign program lacks clear wayfinding, which makes comprehending directional flow difficult. Signage is worn, has gaps in wayfinding, lacks labels for historic sites and buildings, and does not present a true sense of direction or arrival.
Kiosks, trailheads, and trail directional signage is also minimal and requires updating. Additionally, park-specific regulatory signage like STOP, ONE
WAY, DISABLED PARKING, etc., requires updating to meet the current Federal MUTCD standards for size, height, and visibility.
Route 2A (Mass Ave and Merritt Road in Lexington and
North Great Road in Lincoln), plus Lexington Road, Monument Road, Liberty Street, and Barretts Mill Road in Concord are the primary roads to the park’s historic destinations, such as the visitor centers, battle sites, trails, and parking areas at the park. Along the main roadway through the park (Route 2A) several other roads intersect, most notably Route 128/I-95 to the east and Route 2 to the south (Illustration 1).
Illustration 1
3Recommendation Report | Introduction
Since Route 2A is a two-lane public roadway operational 24/7/365, traffic passes directly through the Battle Road Unit of the park on an east/west access at peak times, which can cause a safety risk.
Visitors are often subjected to locals commuting through the park at higher rates of speed. Just as locals are frustrated by visitors who require additional reaction time to determine where parking and other points of interest are located, resulting in slower traffic and congestion. In 2000 the traffic count for this road was 20,000 vehicles per day.
Traffic rates of speed vary from 25-40 mph.
Within the Battle Road Unit, the Battle Road Trail
(Illustration 2) is a 5.5-mile interpretive trail accommodating pedestrians, strollers, wheelchairs, and bicycles. Eight parking lots with designated accessible parking spaces facilitate trail access along the east/west route on the north side of Route
2A and Lexington Road. The Battle Road Trail links various historic sites and landmarks. These include
Meriam’s Corner, historic farming fields, Brooks
Village, Hartwell Tavern, Captain William Smith
House, Paul Revere Capture Site, Minute Man Visitor
Center, and Fiske Hill.
Lexington Road extends west from the Battle
Road Unit to The Wayside Unit and into historic
Monument Square in Concord Center. Monument and Liberty streets extend north to the North Bridge
Unit. Within the North Bridge Unit, the North Bridge
Trail provides access between parking lots, the
North Bridge Visitor Center, Buttrick Gardens, and the historic North Bridge over the Concord River.
Further west, Barretts Mill Road extends through the Barretts Mill Unit, which was added to the park in 2009, and remains without park identity signs.
East of the park is Route 128/I-95 with 100,000 vehicles passing each day with a posted rate of speed of 55 mph. South of the park is Route 2, a four-lane route with 50,000 vehicles passing through each day at a posted rate of speed of 55 mph. Arriving at the park from either Lexington or Concord ends of the linear park necessitates clear wayfinding to and from each site to aid those unfamiliar with the gaps in park ownership.

4Recommendation Report | Introduction
In Concord Center, clear directional signage is needed along roads leading into the Center and to roads leading to the park units. Signs should also distinguish between the park’s visitor center and the town of Concord’s visitor center (Illustration 3).
At gateways into the park, entrance signage is required to present a sense of arrival. From entry points, signs provide further guidance for parking, accessible access, visitor centers, trailheads, restrooms, and other destinations.
The primary Minute Man Visitor Center façade should clearly be identified and welcoming to an unfamiliar visitor upon arrival. At this location, informational and regulations signage should be posted in a prominent location and convey hours of operation
(sunrise to sunset) and other exemptions like no metal detecting or firearms, plus regulations on trash, pets, and bicycle use. The use of international symbols to complement the written messages will assist non-English-speaking visitors. Signage should be inclusive and consider all populations, including disabled and multi-generational.
To summarize, the current signage system is dated and often does not link destinations together as there is a lack of concise wayfinding and direction. Age, weather, and materials used for the construction of these signs have rendered many useless or no longer extant.
The Battle Road Trail signs within the Battle Road
Unit were designed as part of the trail design in the late 1990s and are distinctive with wooden posts, black welded iron frames, fasteners, and post accent bands on wooden posts.
Sign placement, font, size, and materials should be considered, so signage does not detract from the historic battle scene and landscape setting. Signs should evoke a rustic character, similar to what is being asked of MassDOT in their use of timber versus steel guardrails.
Illustration 3
5Recommendation Report | Wayfinding
Vehicular Wayfinding
Visitors will see three sign types as they approach the park Highway Guide Signs, Boundary Signs, and Pathfinder Signs.
The highway guide signs on Routes 2 and 128/I-
95 currently do not feature the correct park name or, where untilized, arrrowhead. It is recommended the signage should be updated to the current standards with correct messages.
A portion of the project that was planned by the
Harpers Ferry Center provides the placement and layout for the park’s boundary signage.
Pathfinder signs will be utilized within the boundary of the park along the main roadway to provide vehicular wayfinding. These signs should identify the locations of parking lots and directional flow to and from the Battle Road Trail, North Bridge Trail, as well as key destinations.

8Recommendation Report | Parking Lot Signage
Parking Lot Signage
A pathfinder sign would be suggested at the entrance of each parking lot to identify the lot and hours of operation.
Many parking lots have faded painted graphics indicating directional flow, accessible parking, etc., on paved areas creating a hazard for traffic flow. It is recommended that these be repainted along with the necessary updates to the signage program to allow the entire system to flow together.

Informational Kiosks
Once parked, a clear list of information as to what can be seen along the way and other posted flyers, maps, and interpretive information should be housed under a covered kiosk sign that is readily visible from the parking area. A one panel or a two-panel kiosk would be recommended, based on content.

11Recommendation Report | Trailheads
Trailheads
At the start of all trails, a trailhead sign is required to identify restrictions, level of difficulty, distance, and attractions along the way. This is a key component, especially for the disabled or physically limited population, as many of the trails are not accessible.
Some of the trails have irregular surfaces, like gravel, yet currently they are identified with an accessible symbol. Verification as to the acceptable terrain should be provided by an accessibility expert prior to the planning of these locations. This is beyond the scope of work for this phase but will be necessary during the planning stage of the project. When it is determined which trails are non-compliant or access is limited, the current signs should be removed and the non-accessible symbol added to the trailhead sign near other warning symbols.
Trailhead Panel
The sample trailhead panels are from other NPS sites and illustrate layouts only, colors and information displayed do don’t reflect final design suggestions for Minute Man National Historical Park.
12Recommendation Report | Trail Markers
Battle Road Trail Markers
Granite obelisks are located along the Battle Road Trail with messaging relating to the visitor’s proximity to either Boston Harbor or Meriam’s Corner. As these markers relate to the entirety of the Battle Road trail rather than the length of the trail within the boundary of the park, it is not recommended that these be altered and that they remain in place.
13Recommendation Report | Trail Markers
Trail Distance Markers
Sections of the trails, most notably the Vernal Pond
Loop, Fiske Hill Loop, Parkers Revenge Loop, and the trail behind the Captain William Smith House that connects to the Hartwell Tavern, do not have distance markers. It is recommended that the 6” x 6” trailside sign should be utilized at 1/10 mile increments along trails.

14Recommendation Report | Trail Markers
Interpretive Trail Markers
Along the trail are a series of markers that are tied into an interpretive brochure. As these markers are weathered it is recommended that the trailside signs be updated to display appropriate destination information.
The 6” x 6” sign should be utilized in areas that only require a number, while the 6” x 18” sign would be used in areas that require a number and small amount of information.

15Recommendation Report | Trail Directional Signage
Trail Directional Signage
Minimal directional signage can be found along the trails ... and what exists is old and difficult to read.
Some of the directional signage leads to points of interest, like historic homes or battlefields. While other locations do not have any current directional signage to clarify one’s location.
While the Battle Road Trail is a well maintained accessible trail, the other trails, such as the Vernal
Pond Loop, the Fiske Hill Loop, the Parkers Revenge
Loop, and the trail behind the Captain William Smith
House that connects to the Hartwell Tavern, are unpaved and not clearly defined and present a major concern. These trails are extremely confusing and offer little to no information as to how to exit them, as they meander through trees in heavily wooded areas. In these instances, a clear message/warning should be conveyed that identifies the conditions and accessibility level of the trail. (Photo 2)
There are some signs that indicate when a trail ends. These signs display a small map to orient a visitor as to how to return to their original point of entry. (Photo 3)

Regulatory Signage
Though not a part of this scope of work, the current regulatory signage located within the park was observed to be non-compliant with state and
Federal codes (MUTCD). These include; STOP, ONE

Accessible Signage: Parking Space Identification
Signage can be found at accessible parking spaces located within the park’s parking lots. These signs are non-compliant with the current MUTCD or ADA standards. They are mounted too low to the ground and the graphics are brown and white, not in the required white and blue colors, with the appropriate symbol. The layout of these signs do not present the text with standard symbol. It is recommended that these signs be updated to the appropriate heights and panels to clearly identify parking for the disabled population.

22Recommendation Report | Accessible Signage: Parking Pavement Markers
Accessible Signage: Parking Pavement Markers
Some parking spaces do not have pavement markers indicating the borders of the parking space and the symbol for accessibility. Many those that do have borders and symbols are faded. These pavement markers should be painted to match MUTCD and
ADA requirements. Though not a part of this scope of work, it is suggested that the pavement graphics be updated to clearly define spaces that will be designated for accessible vehicles.
Van-accessible parking spaces should also be identified with the typical sign for accessibility as well as a secondary sign panel that sits below the accessible sign indicating “Van Accessible.” These parking spaces also require painted lot graphics;
however, they are wider and have a diagonal line pattern that sits to the side of the space to allow for access from a side door of a van.
Except from the Manual on Uniform Traffic Control Devices (MUTCD) Section 3B.19 Parking Space Markings
Support:
01 Marking of parking space boundaries encourages more orderly and efficient use of parking spaces where parking turnover is substantial. Parking space markings tend to prevent emcroachment into fire hydrant zones, bus stops, loading zones, approaches to intersections, curb ramps, and clearance spaces for islands and other zones where parking is restricted.
Standard:
02 Parking space markings shall be white.
Option:
03 Blue lines may supplement white parking space markings of each parking space designated for use only by persons with disabilities.
Support:
04 Additional parking space markings for the purpose of designating spaces for use only by persons with disabilities are discussed in Section 3B.20 and illustrated in Figure 3B-22.
Stroke width:
Minimum = 3 inches Special = 4 inches
Height of symbol:
Minimum = 28 inches Special = 41 inches
Width of symbol:
Minimum = 24 inches Special = 36 inches
Note: Blue background and white border are optional

23Recommendation Report | Room Signage
Room Signage
Room signage, located within buildings and on exterior doors, should be ADA-compliant. Many of the currently located restroom signage does display
Braille and raised letters with the appropriate symbols.
There are also instances where signs are posted on doors. Signs on doors are non-compliant and should not be used. The location of these signs is very specific regarding height and placement from door swings. The ADA clearly mandates how signs should look; acceptable fonts, sizes, use of Braille, mounting and color contrast are identified. The following is an excerpt from the ADA related to how room signage should be executed.

26Recommendation Report | Summary
Summary
In conclusion, this document highlights many of the issues found in the existing signage at Minute Man National
Historical Park and voids within the overall program. It also makes recommendations for upgrades and changes.
As a foundation for the future planning and implementation of permanent signage, considerations has been given to the “keys” of a comprehensive signage program.
Planning Considerations:
1. Who is utilizing the signage?
2. What is the message: Informative, warning, directional, identification?
3. Do signs reflect the NPS Sign Standards for brand and visibility?
4. Where are signs located and how and where do they fit in their environment?
5. Do the signs function?
6. Are signs durable with expanded longevity?
There are four types of signage that together comprise a comprehensive plan: informational, identification, directional and regulatory. Each independently has a separate purpose, together they serve as one unit connecting the overall site and its ease of use.
Signage should be legible, cohesive, inclusive and consistent with the NPS brand and the VIS Sign Standards. The signage program goals are to inform of the park’s rich historic purpose and destinations and the interconnectivity between roadways, parking, trails, visitor centers and other amenities.
Future emphasis on these key aspects for an overall signage plan will afford visitors a truly inspiring experience when exploring all that the Minute Man National Historical Park has to offer.
