About this file
This document is Attachment H to a National Park Service procurement, containing Mass DOT fabrication and installation details for motorist guidance pathfinder signage at Minute Man National Historical Park along the Massachusetts Route 2A corridor in Concord, Lincoln, and Lexington.
The project involves eighteen pathfinder signs total: seventeen signs to be replaced in kind at existing locations and one new sign at Fiske Hill. All signs utilize double breakaway posts with aluminum panels and reflective vinyl featuring a 4-inch cap height. The signs are categorized by location and function: Brooks Village (4 signs), Hartwell Tavern (4 signs), Paul Revere Capture (4 signs), Minute Man Visitor Center (5 signs), and the new Fiske Hill sign (1 sign). Sign sizes vary, with most parking guidance signs measuring 28" x 28" and directional signs measuring 30"w x 34"h or 35"w x 47"h. Each sign location is documented with specific Linear Reference System (LRS) coordinates, GPS coordinates, and detailed location plans with aerial photography. The document specifies that all existing stone wall segments along the corridor, whether within the Massachusetts DOT right-of-way or on park land, will be retained and not altered. The document includes NPS standard aluminum sign fabrication specifications, attachment details, breakaway post specifications following FHWA standard E633-03, and installation safety requirements referencing Massachusetts temporary traffic control guidelines for work zone safety.
