The current Longmont Comprehensive Plan indicates that Boston Avenue is a collector roadway from S. Pratt Parkway to Martin Street. This project included the design and construction of a new roadway from Main Street (US 287) eastward connecting to Martin Street. Construction was completed in 2016.
This connection provides an additional east-west connection between South Pratt Parkway and Martin Street, helping to relieve congestion at the Ken Pratt Boulevard and Main Street intersection. This new roadway also provides access to the 1st and Main redevelopment area and the Southeast Urban Renewal Area.
In addition, the current arterial spacing between 9th Avenue and Ken Pratt Boulevard exceeds the on- mile standard that the City strives to achieve. This results in higher traffic volumes on local and collector streets in the area. The construction of Boston Avenue helps redistribute these traffic volumes.
Immediately to the south of the new Boston Avenue will be the future Dickens Farm Nature Area.
The new roadway cross-section has one travel lane in each direction, a center turn lane and on-street bicycle lanes. Sidewalks on the south side of Boston Avenue will be installed with the Dickens Farm Nature Area project and will slightly detach from Boston Avenue to meander through the north area of Dickens Farm.
In addition to this new leg of Boston Avenue, a new northbound right turn lane onto Boston Avenue is installed on Main Street. This new turn lane connects to Main Street Bridge at St. Vrain Creek.
As part of the project, Boston Avenue from S. Pratt Parkway to Main Street received an asphalt mill and overlay as well as traffic striping improvements.
Traffic studies did not warrant the installation of a new traffic signal at Main Street and Boston Avenue until 2018. In the meantime, the intersection will be managed by a stop sign for traffic crossing Main Street while Main Street remains open.
This project was completed in 2016.
The Boston Avenue Connection Project is exclusively managed by the City of Longmont. Coordination was required with Colorado Department of Transportation for the Main Street right turn lane and proposed traffic signal.
Funding for this project is provided by the ¾ cent Street Fund Sales and Use Tax. The total cost of this project is $3,211,200, which includes all design, right-of-way and construction costs.
