Resurfacing of southern New Hampshire’s major east-west highway is recognized by feds for its innovative features.
A $10 million resurfacing project on Route 101, southern New Hampshire’s major east-west highway, includes so many innovative features the state’s Department of Transportation was awarded a $2 million grant from the federal Highways for Life (HfL) program. This grant is in addition to the Federal Highway Administration’s usual 80 percent contribution under the 80/20 Federal-aid highway funding program.
NHDOT is currently resurfacing the highway between Manchester and Epping, which lies within the agency’s Maintenance District 5. Resurfacing is divided into three projects, the first of which is for a segment of Route 101 from the Manchester-Auburn line to the Auburn-Candia line.
The Auburn-Candia contract involves resurfacing approximately 14.4 miles of highway – 7.2 miles eastbound, 7.2 miles westbound. The divided highway has two lanes in each direction and includes Exits 2 and 3. Rehabilitation of seven bridges along NH Route 101 is also part of the contract. This work consists of a mill-and-fill operation with a 2-inch-thick intermediate course placed in the two travel lanes, followed by a 1.5-inch wearing course installed over both lanes. Other work includes upgrading guardrail, adjusting roadway drainage structures, and pavement work on the Exit 2 and Exit 3 Ramps.
