Road and Bridge Project on NH 101 in Auburn-Candia
Includes Rehabilitation of 7 Bridges Over 7.2 Miles

A pavement and bridge rehabilitation project currently underway on NH Route 101 in Auburn and Candia will feature construction innovations not previously used in New Hampshire, with the goal of extending the life of the pavement surface by an additional three years, or 25% of the normal service life.

The 7.2 mile project extends from the Manchester/Auburn town line to the Candia/Raymond town line. It includes seven bridges as well as Exits 2 and 3. The work will also include upgrading guardrail, adjusting roadway drainage structures, and pavement work on the Exit 2 and Exit 3 Ramps.

Various pavement applications will utilize high amounts of recycled asphalt, an asphalt-rubber mixture, warm mix asphalt technology combined with recycled asphalt, and a "High-Polymer Modified Asphalt", with the overall goal of promoting longevity of the pavement and bridge decks while withstanding heavy traffic. A 15-year surface life is anticipated for each of the pavement mixes, versus the usual 12-year expectation.

The Route 101 project is also utilizing "Smart Work Zone" technology that features changeable work zone speed limit signs, and traffic sensors in the vicinity of paving operations that will trigger "Reduce Speed" signs. Also included in the project will be the installation of "Safety Edge", a paving technique that shapes pavement edges at a 30 degree angle to allow drivers to re-enter the roadway safely.

Lane closures and lane shifts will be required to complete this work. Beginning August 26, there will be night lane closures on Sunday through Thursday nights from 7:00 pm until 6:00 am for paving operations for several weeks. Pike Industries, Inc. of Belmont, New Hampshire is the general contractor for the $13.4 million project, which has a final completion date of October 2013.
