Union Avenue Improvements

The Union Avenue corridor in Laconia is a major part of the City’s business district. Over the past several years, the City has undertaken the reconstruction of various portions of the corridor in an effort to preserve the serviceability of the roadway. The three-lane segment between Lakeport Square and Stark Street had fallen into a state of disrepair. The roadway was experiencing fatigue and cracking due to poor subbase material and inadequate drainage. Additionally, there were substandard pedestrian facilities and a collapsing retaining wall along this portion of the corridor. In an effort to improve safety and longevity of the roadway, BETA designed the reconstruction of Union Avenue. The project includes the rehabilitation of the pavement (reclaim and full depth), upgrade of the sewer, upgrade of pedestrian facilities, installation of new signing, and repair of thecwater and gas utilities.

The Lakeport Square intersection was upgraded to improve traffic flow and increase safety. These improvements included reconstruction of the pedestrian facilities for conformance with ADA standards, modification to the traffic signal parameters, installation of preemption with the nearby railroad crossing, and revision of lane geometry. The Stark Street intersection at the project’s northerly limits has large radii that encourages faster travel speeds from Union Avenue on to Stark Street. Improvements were developed to alleviate vehicle safety deficiencies by reconfiguring the intersection and improving sight lines.
