Active Project - Missoula Van Buren Street Interchange

Missoula East and West Project

Missoula Van Buren Street Interchange

Project Overview

This project in the City of Missoula consists of reconstruction of the Interstate 90/Van Buren Street Interchange to include a 4-spoke roundabout at the eastbound ramp termini and another one at the westbound ramp termini. The project includes noise barrier walls along the north side of the westbound off-ramp and the westbound on-ramp, along with an overlapping segment of noise wall along the westbound shoulder of the I-90 mainline that includes a structure-mounted barrier over Van Buren Street. Other work will include shared use paths along the east and west side of Van Buren, retaining walls, storm drain, lighting, signing, pavement markings, landscaping, and an irrigation system.

The project begins on I-90 at RP 105.3 (the beginning of the eastbound off-ramp) and extends easterly 0.8 miles to RP 106.1 (0.2 miles east of the end of the eastbound on-ramp). On Van Buren, the project will begin at Broadway and extend northerly 0.23 mile to just south of Poplar Street.
