Contractor to begin trench restoration April 28

The Central Avenue North Water Improvements contractor is scheduled to begin trench restoration on Central Avenue between Abbey Sawyer Memorial Drive and Glenwood Avenue on Thursday, April 28.

The work will begin at the Glenwood Avenue and Central Avenue intersection and work south on Central Avenue toward Merry Street next week.

Lane shifts will be necessary and may require alternating one-way traffic. The traffic signals at Central Avenue at Glenwood and Central Avenue at Hannaford plaza will be set to flashing to allow flaggers to control traffic flow.

The trench restoration will improve the travel conditions along that section of Central Avenue. Later this fall, after the soil has had more time to settle, a full pavement overlay of Central Avenue will occur in the project area. The contractor had completed the replacement of the 133-year-old water main in January; however, only a temporary trench pavement could be used due to the weather, leaving many parts of the work area in poor travel condition.

Project overview
The Central Avenue North Water Improvements Project replaced two sections of water mains. One is a 133-year-old, 14-inch water main from Lowell Avenue to Abbey Sawyer Memorial Drive, a critical piece of Dover's water system infrastructure. The other is an undersized six-inch water main from Glenwood Avenue to Lowell Avenue installed in 1927. The contractor replaced both mains with 16-inch ductile iron pipes expected to last the next 100-150 years. The project significantly improves reliability and fire flow capacity in the area and creates a better interconnection between the City of Dover's two water pressure zones.

After a competitive bid process, the City Council awarded the construction contract to N. Granese & Sons, Inc. of Salem, Massachusetts, in June 2021.

Aging water mains were replaced last year along the above section of Central Avenue.
