15 ft. from the edge of pavement.

701006 This standard will be used on 2 lane / 2 way traffic for all work activities within 24 inches to 15 ft. from the edge of pavement.

701301 This standard will be used on 2 lane / 2 way traffic for construction activities such as marking patches, string line operations, utility operations, work zone pavement marking removal, and cleaning debris on the pavement.

701311 This standard will be used on 2 lane / 2 way traffic for construction activities that require continuous moving operations such as pavement marking and raised reflective pavement markers.

701421 This standard will be used any time a lane closure is required on a multilane roadway due to work encroaching on a travel lane adjacent to the shoulder or on the shoulder within 24” of the edge of pavement for day operations only.

701422 This standard will be used any time a lane closure is required on a multilane roadway due to work encroaching on a travel lane adjacent to the shoulder or on the shoulder within 24” of the edge of pavement.

701426 This standard will be used for lane closures on multi-lane roadways for intermittent or moving operations. Typical operations include landscaping work, utility work, and pavement marking.

701501 This standard will be used for all activities on 2 lane / 2 way urban sections requiring a lane closure.

701502 This standard will be used for all activities on 2 lane / 2 way urban sections with bi-directional turn lanes requiring a lane closure.

701602 This standard will be used for all activities involving urban lane closures on multilane, 2 way traffic with a bi-directional left turn lane.

701701 This standard will be used for all work activities involving a multilane urban intersection.

701801 This standard will be utilized for all sidewalk closures throughout the project limits.

BLR 21 This standard shall be used during construction activities which involve a temporary road closure of any city street. This work shall be done in accordance with Section 701 of the Standard Specifications and as per Highway Standard BLR 21.

BLR 22 This standard will be used any time a city street is temporarily closed to thru traffic.

No roadways may be closed without written approval by the City and at least 48 hours notification prior to road closures. In addition to the requirements in this standard, two (2) bi-directional flashing lights will be required on each Type III barricade and both advance warning signs will be equipped with flashing lights and

(1) 18" x 18" orange flag attached above the signs from each direction. This work shall be done in accordance with Section 701 of the Standard Specifications and as per Highway Standard BLR 22.

TRAFFIC STAGING AND CONSTRUCTION SEQUENCING

The Contractor shall provide the Engineer at least two weeks advance notice prior to mobilizing any equipment, materials, or work forces to the project site so that the City of Springfield can notify property owners of the upcoming construction, traffic patterns, signage, etc., and notify the public of any temporary lane closures required. The Contractor shall prepare and submit to the Engineer for review and approval a Traffic Staging and Construction Sequencing Plan consistent with the concept described herein and shown on the details included in the Construction Staging and Maintenance of Traffic Plans to outline the sequence of construction for all of the work shown in the plans. Special attention should be given to the work required to implement the proposed closures and lane shifts needed to install storm sewers and construct pavement widening along the existing portions of W. White Oaks Drive and Hedley Road. The Contractor’s plan will indicate any lane closures and the location of traffic within each stage (day and night) along with any temporary barriers. Work shall not begin until the Contractor’s Traffic Staging and Construction Sequencing Plan is approved in writing by the Engineer.

The Contractor will schedule his work in accordance with the following requirements and in compliance with the Standard Specifications for keeping roads open to traffic. Any deviations proposed by the Contractor to the following Traffic Staging and Construction Sequencing special provision shall be submitted in writing and approved by the Engineer prior to the Contractor making traffic control revisions.

In general the construction sequence shall be as follows:

Stage 1

1. The Contractor shall coordinate utility adjustments for the entire project during this stage and allow relocations by the appropriate utilities to be completed prior to initiating construction.

2. The Contractor shall erect detour signing for the closure of the W. White Oaks Drive and Cascade Drive intersection and the sidewalks adjacent to the intersection.

3. The Contractor shall construct the proposed roundabout intersection of W. White Oaks

Drive with Cascade Drive. The full-depth reconstruction of the intersection along W. White Oaks Drive will start just north of the existing Harvest Market entrance (Sta. 106+13.25) and continue to the north project limits (Sta. 108+79). The Contractor shall maintain access to the existing Harvest Market entrance off W. White Oaks at all times.

4. The Contractor shall construct the roundabout pavement to the top of binder course and temporary pavement marking shall be installed prior to removing the roadway closures.

5. Upon completion of the roundabout pavement to the top of binder course, the Contractor shall remove the roadways closures and detour signing of W. White Oaks Drive and Cascade Drive and open access to the Harvest Market parking lot off the east leg of the roundabout intersection.

Stage 2

1. Once the new access to the Harvest Market parking lot off the east leg of the roundabout intersection is open, the Contractor shall close the existing driveway off W. White Oaks Drive.

2. The Contractor shall mill the existing surface of W. White Oaks Drive and the east leg of Hedley using single lane and partial lane closures. One lane of traffic in each direction shall be maintained at all times unless otherwise directed by the Engineer. Short-term pavement marking shall be utilized until temporary marking can be installed.

3. The Contractor shall shift traffic to west in order to widen existing W. White Oaks Drive pavement on the east side using single lane and partial lane closures. One lane of traffic in each direction shall be maintained at all times unless otherwise directed by the Engineer.

4. Upon completion of widening on the east side of W. White Oaks Drive, the Contractor shall shift traffic to the east side in order to widen existing W. White Oaks Drive pavement on the west side using single lane and partial lane closures. The proposed median inlet and storm sewer crossing at ~Sta. 104+40, Lt. can be constructed and patched without the inlet or the inlet can be partially constructed and temporarily covered with a plate until the raised curb medians are constructed later this stage.

5. Upon completion of the widening of both sides of W. White Oaks Drive, the Contractor shall begin overlaying W. White Oaks Drive and the east leg of Hedley Road with HMA binder in some areas (W. White Oaks Drive) and HMA surface course everywhere including the roundabout intersection of W. White Oaks Drive and Cascade Drive. Traffic shall be maintained using single lane closures and partial lane closures. One lane of traffic in each direction shall be maintained at all times unless otherwise directed by the Engineer. In order to help with the maintenance of traffic, the HMA overlays shall include the areas of proposed raised curb medians and corner islands in order to allow for more usable roadway width. Lane closures on Wabash Avenue will only be permitted during off-peak hours from 9:00 AM to 11:00 AM and from 1:00 PM to 3:00 PM Monday - Friday and 8:00 PM to 6:00 AM Sunday - Thursday without prior written approval from the Engineer.

6. Upon completion of the final HMA surface course lift of W. White Oaks Drive and Cascade Drive, the Contractor shall cut out the existing pavement in the areas of the raised curb medians and corner islands and construct the raised curb medians and corner islands. The proposed median inlet at ~Sta. 103+15 and storm sewer connection to the proposed manhole at ~ Sta. 103+44 shall be constructed during this portion of the Stage.

7. The Contractor shall apply the permanent pavement markings of W. White Oaks Drive, Cascade Drive and the east leg of Hedley Road.

Stage 3

2 The Contractor shall erect the detour signing for the temporary closure of the south leg of the Koke Mill Road and Hedley Road intersection. The existing traffic signals shall be covered as directed by the Engineer to avoid confusion of vehicular traffic during closure of the south leg. The closure of Koke Mill Road shall be limited to four days.

3 Once the detour signing has been erected, the Contractor shall cut a trench across Koke

Mill Road as described in the plans and construct the new storm sewer connection to the existing box culvert running along the west side of Koke Mill Road. The existing storm sewer connection across Koke Mill Road to the box culvert shall be maintained for temporary drainage until the new connection is completed or until it is no longer needed for temporary drainage during Stage 4.

4 Once the new storm sewer connection is completed, the roadway pavement on Koke Mill

Road shall be patched according to the plans.

5 Once the roadway patching on Koke Mill Road is completed, the detour signing and traffic signal coverings can be removed and the south leg of Koke Mill Road can be opened back up to traffic.

6 The Contractor may elect to replace the controller and cabinet at the intersection of Koke Mill Road and Hedley Road at the same time as the proposed storm sewer crossing of Koke Mill Road is being constructed. If the Contractor elects to do so, all the existing traffic signals shall be covered and temporary stop signs shall be erected for all open legs of the intersection. The intersection shall function as an all-way stop controlled intersection until the new controller and cabinet have been installed and the traffic signals are fully functional.

If the Contractor elects to replace the controller and cabinet during another construction stage, the temporary signage and traffic signal covering described above will still be required.

Stage 4

1. The Contractor shall erect the detour signing of the conversion of Hedley Road to one way westbound traffic. The existing traffic signals shall be covered as directed by the Engineer to avoid confusion of vehicular traffic during conversion of Hedley Road to one-way westbound traffic.

2. The Contractor shall shift traffic to the north side of the existing Hedley Road pavement and construct the full-depth pavement to the top of binder course on the south side of Hedley Road from Koke Mill Road to W. White Oaks Drive.

3. Existing storm sewer and pipe culvert crossings shall be maintained, diverted or otherwise dealt with as described in the DEWATERING special provision above. Proposed storm sewer crossings of Hedley Road, which can only be partially constructed, shall be temporarily blocked with plates until the north half of Hedley Road can be constructed later this stage.

4. Access to all businesses and Robbins Road along the south side of Hedley Road shall be maintained at all times using aggregate for temporary access. If there are multiple entrances, access may be provided to one entrance at a time at the discretion of the Engineer. If there is only one entrance, then access will need to be provided by constructing one half of the entrance at a time.

5. Upon completion of the south half of pavement to the top of binder course on Hedley Road, the Contractor shall shift traffic to the south side of Hedley Road and construct the full-depth pavement to the top of binder course on the north side of Hedley Road from Koke Mill Road to W. White Oaks Drive.

6. Access to all businesses along the north side of Hedley Road shall be maintained at all times using aggregate for temporary access. If there are multiple entrances, access may be provided to one entrance at a time at the discretion of the Engineer. If there is only one entrance, then access will need to be provided by constructing one half of the entrance at a time.

7. Upon completion of the pavement to the top of binder course for Hedley Road, detour signing for Hedley Road can be removed and the Contractor shall construct the final HMA surface course lift of both sides of Hedley Road using single lane closures and shifting traffic.

8. The Contractor shall apply the permanent pavement markings on Hedley Road from Koke Mill Road to W. White Oaks Drive.

Post-Stage 4
