Next week, the contractor will begin work by the Hannaford traffic light on Central Avenue and work north to the Glenwood Avenue intersection.
Once crews reach the Glenwood intersection, the outbound Shaw's exit to Glenwood Avenue will be closed and detoured via Morin Street. That work is anticipated to begin Wednesday, Nov. 10 and continue through Friday, Nov. 12. Crews will work on Veterans Day, Thursday, Nov. 11.
Glenwood Avenue traffic by the intersection will be shifted daily to accommodate the construction crew.
Traffic lights will be set to flashing to allow flaggers to control traffic flow.
It is anticipated that Central Avenue will have traffic lanes open in both directions for the week, though there may be times when only one lane is open. Motorists should expect lane shifts.
The contractor anticipates installing the final part of the new main during the week of Nov. 15. Once pipe testing is complete, the contractor will begin connecting water customers to the new water main.
Community Services Deputy Director Bill Boulanger will begin scheduling tie-ins with water users soon.
Driveway access
The contractor has notified residents and businesses in advance when driveway access may be temporarily blocked to complete work. However, the contractor stresses that access can quickly be established when requested. Residents and businesses with specific access concerns should contact Community Services Deputy Director Bill Boulanger at 603-516-6450 or b.boulanger@dover.nh.gov.
Project overview
The Central Avenue North Water Improvements Project replaces 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 the City of Dover’s water system infrastructure. The other is an undersized six-inch water main from Glenwood Avenue to Lowell Avenue installed in 1927. Both mains will be replaced with 16-inch ductile iron pipes that are expected to last the next 100-150 years. The project will significantly improve reliability and fire flow capacity. The improvements will also provide better interconnection between the City’s two pressure zones, increasing the water system’s reliability throughout the City.
The project is anticipated to be substantially complete by mid to late December, weather permitting. A complete street paving overlay will occur next spring.
After a competitive bid process, the City Council awarded the construction contract to N. Granese & Sons, Inc. of Salem, Massachusetts, the same contractor as the Washington and Main Water Improvements Project.
The project is expected to create traffic backups in and near the project area. Residents and businesses in the construction area with questions or concerns should contact Deputy Community Services Director Bill Boulanger at b.boulanger@dover.nh.gov or 516-6450. Boulanger is the project manager.
