The City has recently begun work on reconstruction of the tunnel on Cambridge St at the northern end of Harvard Yard.  This is a major infrastructure project to address structural conditions within the tunnel.  The most significant improvements will include:

  • Drainage work and waterproofing the top slab.
  • Replacement of the tunnel wearing surface.
  • Repairs to the roof, center and exterior walls.

 

Alterations to the surface of the overpass are necessary to allow for construction access during reconstruction of the tunnel.  The City and Harvard University are coordinating with regard to plans to restore and improve surface conditions on the overpass that will be affected by the repairs to the tunnel.  The scope of the proposed alterations within the historic district include widening and repairs to the brick City sidewalk at the curved approach to the overpass at the northwest corner of Harvard Yard and removal of a concrete planter and railing at the edge of the overpass.  The planter will be replaced with surface concrete pavers and two benches, while an edge wall will replace the existing railing to ensure safety as well as define the boundaries of the overpass.

These alterations will improve the safety conditions for the many pedestrians and cyclists who use the overpass by creating an even surface on the brick public sidewalk, removing barriers to visibility and reducing conflicts between pedestrians and cyclists.

Please visit Harvard University's construction website to learn more about the surface improvements and schedule.
