Downtown Project

Construction Info

Current Phase: Construction Ongoing

The City’s Downtown Project continued with significant progress throughout August:

• Liberty Utilities completed the replacement of approximately 800 feet of older steel gas mains with new 8-inch HDPE lines on the east and west sides of Central Square.  
• Casella Construction, Inc., the City’s construction contractor, completed their exploratory excavation at critical utility connection points in Central Square, then quickly shifted to the installation of new water main on the west and north sides of Central Square.  Additionally, they made preparations for continued construction activities, including the removal of light poles, granite curbs, and bollards.  Tree protection fencing and trunk protection for trees adjacent to active construction was installed, three trees were transplanted to a new location within the city, and several trees within the immediate construction zone were removed.

Throughout September, Casella’s primary focus will be on the replacement of water and sewer mains around Central Square. 

Helpful Information

• Project Phasing Plan – 2026, 2027, and 2028
• Design Visualization – an interactive visual aid showing design info
• Traffic – at least one lane in each direction will be maintained throughout the construction area. When detours are necessary, that info will be posted here.
• Parking Guide – Parking spaces will remain open throughout construction except when they are actively under construction. The public parking lots on Gilbo Ave. and Commercial St. are the best parking options as close to downtown businesses as many of the on-street parking spaces, and the time limits are longer and the fees are lower.
