Construction Update

The contractor, Castle Rock Construction, will start major roadway construction activities as soon as March 1, and travel impacts and delays are expected.




Weeks of March 1 and March 8

For the next two weeks, Monday - Friday, March 1-5 and March 8-12, from 7 a.m. to 6 p.m. daily, crews will be conducting preliminary construction activities (locating utilities) on 120th Street and on the north side of S. Boulder Road between Round Table Drive and Malory Street. Motorists can expect intermittent single-lane closures within the construction work zone.


120th Street Impacts

Starting as soon as mid-March, 120th Street, south of S. Boulder Road, will temporarily be a single lane roadway with alternating traffic. A temporary traffic signal will assist motorists through the single lane portions of 120th Street. This impact is expected to last several months and motorists are encouraged to use an alternate route.


Initial construction activities will likely involve temporary detours and traffic impacts. Please follow this page for specific construction updates and traffic impacts. The project team will also send email updates and post on Facebook and Twitter.


Please use caution in the work zone and follow construction signage. Construction schedules are weather-dependent and subject to change.


Project Overview

The City of Lafayette’s S. Boulder Road Multimodal Improvements project will enhance safety and multimodal travel for all users along this corridor. This project includes improvements to S. Boulder Road, between the Saratoga/Merlin Drive intersection and 120th Street, with minor work on City Center Circle and on 120th Street, between approximately Eastwind Drive and Coal Creek.


Project work includes:

  • Improving S. Boulder Road from the Saratoga/Merlin Drive intersection to 120th Street to accommodate a center turn lane, bike lanes, and a new 6-foot-wide sidewalk along S. Boulder Road.

  • Constructing a new multi-use path (10-foot-wide sidewalk) along the south side of S. Boulder Road from the Saratoga/Merlin Drive intersection to 120th Street to improve multimodal connectivity to Alicia Sanchez Elementary School.
    1. Intermittent sidewalk improvements along City Center Circle from S. Boulder Road to the RTD Park-n-Ride.

  • Reconstructing the LaMont Does Park parking lot.

  • Burying overhead power lines along S. Boulder Road.

  • Constructing a new signalized intersection at S. Boulder Road and 120th Street, and widening 120th Street at this intersection.

  • Improving drainage along S. Boulder Road and 120th Street.




Schedule:

Construction will begin as soon as March 1, 2021 and is estimated to continue through early 2022.


Funding:

This is a City of Lafayette project, funded by a Colorado Department of Transportation grant, Boulder County’s countywide transportation sales tax and City of Lafayette road funds.
