Lancaster Intersection Improvements on Route 117/Route 70 at Lunenburg Road & Route 117/Route 70 at Main Street

Project Description, Schedule, Traffic Management, and Critical Path/Baseline Schedules

Project Description

  • The work under this contract consists of safety and traffic operation improvements along approximately 3,155 feet of Main Street / Seven Bridge Road (Route 117), 390 feet of Lunenburg Road (Route 70), and 275 feet of Main Street (Route 70). There will also be some minor paving along Shirley Road (approximately 50 feet) and minor realignments of Otis Street and Buttonwood Lane at Route 117.
  • The project also includes a new drainage trunkline that will run the length of the project and extend roughly 800 feet past the limits of full depth roadway reconstruction. This new drainage will outfall just east of the bridge over the Nashua River.
  • The proposed improvements include the construction of enhanced bicycle and pedestrian accommodations. Proposed 5.5 feet sidewalks will begin at the limits of full depth roadway construction and extend to the intersection of Seven Bridge Road and Main Street.
  • An 8-foot cement concrete shared use path is proposed along the south side of Route 117 from the intersection at Lunenburg Road all the way to the Mary Rowlandson School driveway.
  • A bicycle friendly 4-foot shoulder is proposed along the north side of the roadway and a 4-foot shoulder is proposed along the south side of the roadway west of the intersection of Route 117 and Lunenburg Road.
  • Two new traffic signals will be constructed at the intersections of Main Street /Lunenburg Road and Main Street/Seven Bridge Road. The mid-block pedestrian crossings will be removed and the new signals will provide pedestrian actuation for safer roadway crossings.
  • New MUTCD compliant signs and pavement markings will be installed.
  • The work also includes, but is not limited to, earth excavation, pavement fine milling, Superpave asphalt pavement, cement concrete sidewalk, granite curbing, drainage system and utility modifications, tree planting, tree protection, tree removal / pruning / trimming, and other incidental work.
    • Much of the tree trimming and tree removal is to provide adequate space to widen the roadway and relocate the existing utility poles away from the road.
