Longmont expects to begin intersection improvements and reconstruction work at First Avenue and Emery Street on Monday, a project being coordinated with rail crossing improvements by BNSF, city officials announced Friday.

The overall project, expected to last about six months, will reduce lane widths along First at Emery and cause occasional delays for travelers as equipment moves in and out of the work area.

Emery will be closed to through traffic between First and Second avenues, and the city has recommended that travelers use Second Avenue 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.

Once completed, the intersection will feature such safety enhancements as traffic and pedestrian signals, marked crosswalks and stop lines, and sidewalks. Emery Street will include a center divided median north of the railroad tracks.

“This rebuilt intersection will provide a smoother, safer crossing for vehicles, pedestrians and cyclists,”  Micah Zogorski, a city senior civil engineer, said in the city’s news release.

The roadway improvements portion of the project is being completed by Platteville-based Mountain Constructors.

BNSF will replace the three-track crossing with smoother, concrete-surface crossing panels and will install signal gates and flashing lights at the Emery Street railroad crossing. These railroad safety features will help facilitate future quiet zone designations within the city, officials said — crossings where trains no longer have to blare their horns as they approach them.

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.
