Issue 6 | November 2019
Along about seven miles of Route 7, we're adding a third lane and shared-use paths in each direction, building a pedestrian underpass to access Colvin Run Mill Park , replacing and raising the bridge over Difficult Run, and making many intersection, bicycle and pedestrian improvements. Learn more.
Construction and Design Updates
In October, crews made major strides on construction including:

  • Completing and opening a new shared left-turn and through lane on southbound Towlston Road, providing 250 feet of space to vehicles turning onto eastbound Route 7 or crossing Route 7 to continue on Towlston Road. The original target for these improvements was Summer 2020. Read more>>

Pedestrian and Cyclist Safety

As work progresses in the coming months, crews will be working in close proximity to shared-use paths along the corridor. Please watch for signs and barriers indicating travel routes, and be alert to flaggers who may be directing foot and bike traffic through an active work zone. Other tips for negotiating paths near the construction include:

  • Keep your distance, and when possible, avoid walking near areas where crews are actively working.
  • Avoid distractions like cell phones.
  • Wear clothing that increases your visibility, particularly in the evening and early morning.
  • Stay outside of all temporary barriers. Never attempt to cut corners by walking or biking through the work zone.
  • Follow all directional signage.
  • Be aware that temporary paths may not be paved and use caution.
  • When walking past a work area where equipment is being used, make sure the crew can see you, and maintain visual contact until you are well past the work area.
