All Railroad Quiet Zones in the City of Boulder Officially Established as of April 30

Beginning at 7 a.m. on April 30, all railroad “Quiet Zones” work will be completed and the following railroad crossings will be officially established as Quiet Zones:

  • 47th Street
  • 55th Street (north of Arapahoe Avenue)
  • 63rd Street (north of Arapahoe Avenue)
  • Pearl Parkway
  • Valmont Road (established since 2019)

Quiet Zones address the impact of train horn noise on surrounding neighborhoods and businesses through physical infrastructure that allows train engineers to pass through railroad crossings without needing to sound train horns. Train engineers still have the authority to sound the horn if unsafe conditions exist.

Creating the Quiet Zones involved roadway improvements managed by the City of Boulder and railroad improvements managed by BNSF Railway, which owns the right-of-way at railroad crossings in the city. The final step in the process was the approval of the new infrastructure at all five crossings by the Federal Railroad Administration (FRA) and the Colorado Public Utilities Commission (PUC). 

The city also partnered with Boulder County to complete a Quiet Zone at the crossing on 63rd Street at the Diagonal Highway as part of the county’s effort to establish seven Quiet Zones along SH-119 in December 2020.

Funding to design and construct Quiet Zones comes from a $1 million grant from the Denver Regional Council of Governments (DRCOG) with a local match of $200,000 from the City of Boulder transportation fund.
