Project Overview

Current Project Status

Construction on the 27th Street Improvements Project resumed in mid-April 2020. Electrical and sidewalk work began at Montana Avenue and has continued to move north in one to two block increments. Electrical and sidewalk work in August will continue in the area between 7th Avenue North and Rimrock Road. It is anticipated that this work will conclude on the north end of the project this month and that sidewalk and electrical work will move to south of the railroad tracks/Montana Avenue early in September. Paving is not anticipated until October/November of 2020.

Construction results in shoulder closures, single lane traffic for 2-3 block distances, and 1-2 block detours for pedestrians in the designated work areas. All traffic (including pedestrian traffic) should expect detours from lanes and sidewalks and related short delays.

The 27th Street Improvements project began construction in September 2019. The project includes new asphalt for approximately 3 miles of 27th Street through the heart of downtown Billings, from the 27th Street Bridge over I-90 to just south of the Airport Road roundabout. This road provides primary access not only to the downtown Billings businesses, but also the medical corridor (Riverstone Health, Billings Clinic, and SCL Health), MSU-B, and the airport.

The project includes rehabilitation (mill and overlay) of the asphalt roadway, upgrades of curbs to meet the Americans with Disabilities Act (ADA) requirements, replacement of all existing streetlights with LED lights, and replacement of signals at 11 intersections. New signing and striping is also included.

The 27th Street Improvement project maintains and improves the condition of the roadway and extends the service life/quality of 27th Street. It also improves ADA and overall pedestrian access, and upgrades signal systems and lighting, increasing overall safety in the Billings downtown corridor.

Construction is expected to take two full seasons (2019 and 2020), resulting in completion the fall of 2020.
