Valmont Road and 34th Street Improvements

Valmont Road Reopened to Through-Traffic Nov. 21

Valmont Road between 30th Street and Foothills Parkway reopened to through-traffic for all users the evening of Nov. 21, with one lane open in each direction at the railroad crossing.

  • The outside eastbound and westbound lanes are expected to reopen by Dec. 21, weather dependent. 
  • Please note that the roadway approaches to the new railroad crossing are not yet complete but are scheduled to be finished by the week of Dec. 2, weather dependent. 

The outside lanes remain closed to complete underground utility repair and complete sidewalks, lane widening and the retaining wall at the northwest corner of 34th Street.

The remaining signal installation work is anticipated to begin in February 2019. We will provide schedule updates as construction progresses. 

Ongoing construction may cause delays, and travelers are encouraged to seek alternate routes when possible.

Crews have been working hard to complete a lot of work in a short amount of time. Thank you for your patience during this work to create a smoother, safer railroad crossing and multimodal corridor!

Improvements to Valmont Road

BNSF Railway is replacing the deteriorated railroad crossing surface and installing new signals on Valmont Road between 34th Street and Wilderness Place.

The City of Boulder is also making the following improvements to Valmont Road between 34th Street and Wilderness Place, some of which were identified and are being paid for by the S’Park development:

  • Widening the bike lanes on the north and south sides of Valmont from 34th Street to Wilderness Place,
  • Installing a new traffic signal at 34th Street and Valmont,
  • Adding a southbound 34th Street left-turn-only lane onto Valmont,
  • Transit stop improvements, and
  • Adding a new curbed center median to provide for a future railroad quiet zone (railroad crossing that is constructed so that trains do not have to sound their horn).

With all of these components, the street may appear piecemeal until final resurfacing can be completed in summer 2019 or 2020.

Following completion of these improvements, the railroad crossing at Valmont Road will be quiet zone compliant in advance of a separate railroad quiet zone project.
