Work Beginning on US 4 Bridge Replacement in Lebanon
Over Mascoma River at Intersection With NH 4A

The New Hampshire Department of Transportation announces the beginning of construction work on the replacement of the US Route 4 bridge over the Mascoma River at the intersection with NH Route 4A in Lebanon.

Tree clearing work begins on Monday, July 7, 2014, followed by earthwork, drainage, and bridge construction. Construction work will continue into next year. By late fall of 2015, the new bridge will be opened and the existing bridge will be removed.

Traffic will remain on the existing bridge while the new bridge is being built adjacent to it. Excessive delays or detours are not anticipated. Motorists traveling through the project area should use caution and be aware of changing conditions and possible stopped vehicles. Occasional one-way alternating traffic control should be expected.

Along with the realignment of US Route 4 onto the new bridge, the intersection of US 4 and NH Route 4A will be reconfigured for improved safety and sight distance. Upgraded drainage will include two detention basins designed to improve highway runoff water quality.

The US 4 bridge over the Mascoma River also goes over the New Hampshire Rail Trail. The trail will remain open throughout the construction, except during times when it is unsafe for travel due to structural steel erection or bridge demolition work. The trail will remain open during winter months for snowmobile traffic.

Audley Construction, Inc. of Bow, New Hampshire is the general contractor for the $8.9 million project, which has a final completion date of summer 2016.
