Project Overview
What is the scope of this project?
The City of Lebanon is in the design phase for the replacement of the NH 120 Bridge over the NHRR, Bridge, #121/117. This bridge abuts the tunnel that was just reconstructed in the downtown mall area.
The City’s Engineer (Hoyle, Tanner & Associates, Inc.) is in the process of completing the preliminary design for the replacement of the existing bridge.
The purpose of the project is to replace the red-listed, structurally deficient, roadway bridge with a safe structure that will accommodate multi modes of traffic with the recommended vehicular loadings and provide a safe connection to the tunnel for walking and biking.
The bridge and the tunnel will be closed during construction.
How long is this going to take?
The project will take approximately 5 months to complete and is anticipated to start in the Spring of 2025.
Which streets are involved?
The closure will impact the NH120 roadway and some parking in the upper section of the mall parking, as well as the tunnel for safety reasons. Traffic is anticipated to be detoured for a short distance around the newly anticipated roundabout at the High Street, Mascoma Street, and Mechanic Street intersection.
Detours for pedestrians and bicycles will also be accommodated.
How will I know what is happening?
Public informational meetings and discussions will be occurring during the design process and web alerts, for those signed up, will notify any changes and project schedules during the construction process. Direct abutters will be notified if any construction activities will be impacted or traffic pattern changes that would impact parking or clients/employees reaching the mall businesses. It is important to sign up for the alert system for this project page to keep up with the latest information on the progression of the project.
