NH Route 11 Corridor Study

Rochester, NH

Project Summary

With the continuing development of commercial parcels along NH Route 11 (Farmington Road) corridor, the City of Rochester is looking to ensure that safety and mobility of pedestrian, bicycle, and vehicular traffic is maintained. The increased traffic from these developments and the roadway’s use as a key arterial providing access from the Spaulding Turnpike to the Lakes Region has resulted in nearly 20 accidents over a 10-year period on this short stretch of road, with over 50% resulting in injury. Hoyle Tanner was tasked by the City with performing an engineering study to evaluate corridor operations and safety to help alleviate these concerns. 

Our Team’s efforts included traffic capacity analysis, network crash history evaluation, development of conceptual improvement alternatives (including a new traffic signal and additional travel lanes), opinions of probable cost, traffic control considerations, and preparation of a report documenting our findings and recommendations. The design alternatives focused on a potential near-term solution to improve pedestrian and vehicular safety, while a longer-term improvement focused on increased capacity.  

Hoyle Tanner worked closely with the City and the Strafford Regional Planning Commission to get funding for construction prioritized in the State Ten Year Plan. This will allow Rochester to continue to increase its tax base through development while eliminating the traffic bottleneck and safety concerns that have arisen along this corridor.
