Glenville Corridor Traffic Improvements

Glenville Street and Glenville Road Corridor Traffic Improvements Project Drawing

Project Overview

This project was created to reduce congestion, improve air quality, and implement safety measures for motorists, bicyclists, and pedestrians along the Glenville Corridor. The Glenville Corridor experiences heavy commuter traffic due to the proximity to the Merrit Parkway/Hutchinson Parkway via King Street and I-684 via Riversivlle Road. Additionally, there are two private schools located on King Street and one public school located on Riversville Road that generate morning peak hour traffic through the Glenville Road and Glenville Street Corridor. 

Project Location

The Glenville Corridor distance is approximately 1,500 feet which begins at the intersection of Glenville Street and Glen Ridge Road and continues east concluding at the Glenville Road and Weaver Street intersection.

Proposed Corridor Improvements 

A. Glenville Street at Shopping Center Driveway

  • Widen the Glenville Street segment from the shopping center driveway to Angelus Drive to provide a longer westbound right-turn lane into the shopping plaza while maintaining parking along the northern edge of Glenville Street. Additionally, provide a dedicated eastbound left-turn lane into Angelus Drive. 
  • Provide new sidewalks along the southern edge of Glenville Street.
  • Realign crosswalks and reconfigure ramps for Americans with Disabilities Act compliance.
  • Install new traffic signal equipment.
  • Relocate the parking in front of Brighton Cleaners further south on Glenville Street away from the intersection

B. Glenville Street at Riversville Road

  • Extend the raised island on Riversville Road to better control gas station access in and out of the Sunoco gas station.
  • Tighten the northeast corner radius to slow down vehicles negotiating the right turn from Glenville Road to Riversville Road.
  • Install new traffic signal equipment.
  • Maintain the existing Webster Bank entrance-only driveway at Riversville Road.
  • Maintain but signalize the existing stop sign-controlled Webster Bank drive-through.
  • Reconstruct and better define the existing parking spaces along both sides of the east leg of Glenville Road.

C. Glenville Road at Pemberwick Road

  • Install a traffic signal at this intersection.
  • Widen Pemberwick Road to provide dedicated left and right-turn lanes. 
  • Widen the eastern leg of Glenville Road to provide a dedicated westbound left-turn lane and a through lane. 
  • Provide sidewalks and new crosswalks to improve pedestrian access at the intersection.
  • The proposed geometric improvements would result in the elimination of the parking area in front of Glenville Pizza.

D. Glenville Road at Weaver Street 

  • Widen the western leg of Glenville Road to provide a dedicated right-turn lane and an eastbound through lane. 
  • Widen Weaver Street to provide dedicated left- and right-turn lanes.
