Glenville Rd/St Corridor Traffic Improvements

The Town of Greenwich has initiated concept plans for the Traffic Signal Optimization and Intersection Improvements along the Glenville Street/Glenville Road Corridor for a distance of approximately 1,500 feet. Funding for this project is provided under the Congestion Mitigation and Air Quality Improvement Program (CMAQ) with 100% Federal funds administered by the Connecticut Department of Transportation. The Town has selected Milone and MacBroom, Inc. for the design of this project.

The Town conducted the 1st Public Information Meeting on Wednesday, March 20, 2019 at 7:00 p.m. at the Bendheim Western Greenwich Civic Center. Meeting materials from the 1st meeting are attached. 

The Town conducted the 2nd Public Information Meeting on Tuesday, May 21, 2019 at 7:00 p.m. in the lower room of the Bendheim Western Greenwich Civic Center, 449 Pemberwick Road, Greenwich, CT 06831. A print out of the Power Point Presentation from the 2nd meeting are attached. 

Difference between the 3 Preliminary Concepts:


Preliminary Corridor Concept 1:

Preliminary Concept 1 was identified as having the least right-of-way (ROW) impacts and potential for environmental permits. The proposed corridor improvements would be as follows:

i. Glenville Street at Shopping Center Driveway
          a. 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. The proposed widening would be accommodated within the existing ROW with no impacts.
          b. Provide new sidewalks along the southern edge of Glenville Street.
          c. Realign crosswalks and reconfigure ramps for Americans with Disabilities Act compliance.
          d. Install new traffic signal equipment.
          e. Relocate the parking in front of Brighton Cleaners further south on Glenville Street away from the intersection. 

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

 iii. Glenville Road at Pemberwick Road
          a. Install a traffic signal at this intersection.
          b. Widen Pemberwick Road to provide dedicated left-and right-turn lanes. This improvement will result in ROW impacts to the park in the southwest corner of the intersection. 
          c. Widen the eastern leg of Glenville Road to provide a dedicated westbound left-turn lane and a through lane. 
          d. Provide sidewalks and new crosswalks to improve pedestrian access at the intersection.
          e. The proposed geometric improvements would result in the elimination of the parking area in front of Glenville Pizza.

iv. Glenville Road at Weaver Street
          a. Widen the western leg of Glenville Road to provide a dedicated right-turn lane and an eastbound throughlane. This will result in ROW impacts to the Civic Center ball field.
          b. Widen Weaver Street to provide dedicated left- and right-turn lanes.
          c. Provide sidewalks and new crosswalks at the intersection.
          d. Install new traffic signal equipment. 

Preliminary Corridor Concept 2: 

Of the three preliminary concepts, Concept 2 was identified as having moderate ROW impacts and potential for environmental permits. The proposed corridor improvements would be as follows:

i. Glenville Street at Shopping Center Driveway
          a. Same as Preliminary Concept 1 

ii. Glenville Street at Riversville Road
          a. Same as Preliminary Concept 1 with the exception that the Webster Bank entrance-only driveway at Riversville Road would be reconfigured to two-way access. This will involve reconfiguring the existing parking lot, resulting in a net loss of about six parking spaces. 

iii. Glenville Road at Pemberwick Road
          a. Same as Preliminary Concept 1 except that widening is also proposed on the western leg of Glenville Road to provide a dedicated eastbound right-turn lane and a through lane.  This will result in further ROW impacts to the park in the southwest corner of the intersection.

iv. Glenville Road at Weaver Street
          a. Same as Concept 1 with the exception that the eastern leg of Glenville Road would also be widened to provide a dedicated left-turn lane and westbound through lane. This will result in further ROW impacts to the Shell gas station at the southeast corner.

Preliminary CorridorConcept 3:

Of the three preliminary concepts, Concept 3 was identified as having the most ROW impacts and potential for environmental permits. The improvements would be as follows:

i. Glenville Street at Shopping Center Driveway
          a. Same as Preliminary Concepts 1 and 2

ii. Glenville Street at Riversville Road
          a. Same as Preliminary Concept 2 

iii. Glenville Road at Pemberwick Road
          a. Install a new single-laneroundabout at this intersection. This option would result in significant impacts to both the park and ball field at the southwest and southeast corners of the intersection.
          b. Provide crosswalks and sidewalks at the new roundabout for safe pedestrian access.
          c. This concept would also result in the loss of parking in front of Glenville Pizza.

iv. Glenville Road at Weaver Street
          a. Same as Preliminary Concept 2

Next Steps:

The Town is planning to:
• Engage critical business within the corridor that could be impacted.
• Select a preferred corridor improvement concept based on public feedback.
• Hold a third public informational meeting to present the preferred concept.
• Proceed to design following acceptance of a preferred corridor improvement concept.

If you were unable to attend this meeting, are a user of this corridor and would like to share your concerns and recommendations for improvement, please forward your comments to gcohee@greenwichct.org so that your input can be reflected in the project’s development.
