Construction Impacts

Campus Drive Athletic Fields

Quirk began construction of the new field on October 9. Work continues to spring.

Congress Street

Utility replacement on Congress Street began on January 5, 2026 and is expected to extend to early June. Work includes the full replacement of sewer collection, water distribution, and stormwater infrastructure from Maplewood Avenue to a point approximately 100’ beyond (East) of the Fleet Street intersection. For the week of February 16: No work is planned on Monday, Presidents' Day. For the balance of the week, work is anticipated (weather permitting) to include:  1) Installation of sewer service line along Congress towards Maplewood Avenue and 2) Temporary water service installation between Fleet Street and Maplewood Avenue.

The project work proceeds towards Maplewood Avenue with the sewer and drainage installations before moving on to begin work between Vaughan Mall and Fleet Street.  This portion of work will also include the restoration of Congress Street in the fall of ’26 beginning after Labor Day. Work is scheduled to take place daily, Monday through Friday but there may be brief interruptions if conditions become too severe for crews to work effectively.  

A pre-construction public information meeting for the project was held on December 9, 2025. For more information, visit the meeting presentation, the video recording of the meeting and the project page.
