and website updates cannot keep up with moment to moment conditions. This applies to detours which are set daily in the field by Town personnel in conjunction with the Lexington Police Department.

  • 2017 Paving Program (posted 4/27/17) See map for streets on this year's paving list. Again this year, we will be using many different paving and surfacing techniques.  The map has the streets color coded to clarify which streets will receive which treatments.  You can read a description of types of surfacing here. Crews have begun prepping: marking out, lowering the castings and plating, on John Benson, Wright, Bicentennial and Freeman as well as all the roads to be milled.  The week of May 2nd reclaiming will begin on the roads that have been prepped in this phase and around mid May milling on the roads scheduled to be milled will begin.  A more accurate schedule will be posted here once one is assembled. As always, please use patience and caution navigating through construction areas.  Once paving operations begin, a detour map will be posted.  


  • Minuteman Commuter Bikeway Sign and Pavement Marking Project (posted 4/21/17) This project includes fabrication and installation of street signs and roadway markings along the bikeway and at crossings.  


  • Pleasant Street Sidewalk Project (posted 10/18/16)  Project includes installation of a sidewalk along the western side of Pleasant Street from the Wilson Farm driveway to Dover lane.  This section of proposed sidewalk will provide an interconnection link to existing sidewalks therefore providing a continuous sidewalk from Massachusetts Avenue to Concord Avenue.
