The 1st Avenue and Emery Street Intersection Improvements project includes intersection improvements, new traffic signal installation and rail crossing improvements at 1st Avenue and Emery Street.

The current intersection and railroad crossing is marked only by stop signs and simple X-shaped white and black railroad signs known as Highway-Rail Grade Crossing or Crossbuck signs.

The roadway improvement portions of the project are being completed by the City of Longmont and its contractor. Railroad improvements will be completed by BNSF.

Goals and Planned Improvements

Planned improvements will provide safety enhancements for both the intersection and the railroad crossing.

The completed intersection will include traffic and pedestrian signals, marked crosswalks and stop lines, and sidewalks. A center divided median will be added to Emery Street north of the railroad tracks.

BNSF will replace the 3-track crossing with smoother, concrete-surface crossing panels and install signal gates and flashing lights at the Emery Street railroad crossing. These railroad safety features will facilitate future quiet zone designations within the city.


Work is anticipated to begin Monday, April 13, and last approximately six months. The road construction project will be completed in coordination with rail crossing improvement work by BNSF.

Traffic Impacts

Travelers can expect reduced lane widths along 1st Avenue at Emery Street as well as occasional delays due to equipment moving in and out of the work area.

Emery Street between 1st and 2nd Avenues will be closed to through traffic for the duration of the project. Second Avenue is recommended as a detour route.

Portable message boards, detour signs and flaggers will help with navigation. Access to area businesses will be maintained throughout the reconstruction.

Project Costs

Platteville-based Mountain Constructors has been awarded the contract for the roadway portion of the project. BNSF will complete the railroad-related improvements.

Total cost for the project is estimated at $2.4 million, which includes approximately $1.4 million for the roadway work and $1 million for railroad surface crossing improvements and new railroad signals and gates.

Funding comes from a combination of federal and local development funding, along with matching funds from the City’s 3/4-cent Street Fund Sales and Use Tax.
