New Phase of the Arch Street Corridor Traffic Improvements Project to Commence Monday, Nov 1

The next phase of the Arch Street Corridor Traffic Improvements Project begins on Monday, November 1. There will be intermittent lane closures that will take place both day and night for a two-week time span in order to prevent a backup of vehicles exiting off of I-95 and on the already congested Arch Street.

With approximately 35,000 vehicles traveling on Arch Street per day, this project aims to mitigate traffic congestion and improve air quality. The Arch Street Corridor Traffic Improvements Project focuses on five signalized intersections including one pedestrian crosswalk. To improve the traffic an Adaptive Signal System will be installed. This intelligent software responds to the traffic demand in real-time by continuously optimizing signal timings by detecting the actual vehicle volume and identifying traffic coming from the surrounding intersections.

The project area and physical changes in phase 2 include:

  1. Arch Street & Horseneck Lane
  2. Arch Street & I-95 Southbound Ramps
  3. Arch Street & I-95 Northbound Ramps
  4. Arch Street & Railroad Avenue
  5. Arch Street & Steamboat Road/Museum Drive – The Southbound Steamboat Road approach will be modified to include an exclusive right turn lane due to the high volumes making this turning movement.

During this phase, all mast arms, traffic signals, detection equipment, and cabinets will be replaced. This project received funding through the Federal Highway Administration’s Congestion Mitigation and Air Quality (CMAQ) program grant. Be sure to stay vigilant for signage and observe directions from police officers directing traffic.

For the safety of the workers please stay alert, slow down, and drive the detoured route. To learn more about this project please visit the Department of Public Works’ webpage or click HERE.
