The state begins several bridge repair projects this week.
They include work on the Route 13 bridge over the Piscataquog River in New Boston, and a bridge on Route 2 in Randolph that passes over the Moose River.
Bill Boynton of the New Hampshire Department of Transportation says in addition to repair and maintenance work, the state has a number of new bridge projects for contractors to bid on.
"We're advertising to address eight redlisted bridges, and our Bridge Maintenance Bureau has also targeted nine redlist bridges for this calendar year," Boynton says.
The largest bridge project is the one to replace the Sarah Mildred Long Bridge between Portsmouth and Kittery, Maine.
New Hampshire and Maine are splitting the cost of the $173 million dollar replacement span, which is expected to open next year.
