Central Avenue trench restoration continues

The Central Avenue North Water Improvements project contractor will continue trench restoration on Central Avenue between Glenwood Avenue and Abbey Sawyer Memorial Drive next week. Completing the work will require lane shifts, alternating traffic and detours, depending on where the contractor is working. Motorists should anticipate delays. 

Planned traffic control schedule for the week of May 2
 
Monday, May 2 through Tuesday, May 3

  • Work is planned from Glenwood Avenue to Merry Street; 
  • Lane shifts will be necessary and may include one-way traffic alternated by flaggers. 
 
Wednesday, May 4 through Friday, May 6 
 
  • Work is planned from Merry Street to Lowell Avenue; 
  • One-way traffic alternated by flaggers will be required. 
 
Friday, May 6
 
  • If ahead of schedule, work will occur from Lowell Avenue towards Abbey Sawyer Memorial Drive; 
  • Southbound Central Avenue traffic will be detoured around the work area via Lowell Avenue and Mount Vernon Street; 
  • Northbound traffic will proceed through the work area; lane shifts are expected. 
 
The schedule may change depending on weather and work conditions. 

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 will occur in the project area. For more information, contact Community Services at 603-516-6450.  
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 was a 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. The final part of the project is trench restoration and paving.

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