Since its grand opening in 2017, the South Reserve Pedestrian Bridge has been used by tens of thousands of commuters, recreationalists, and bicycle tourists to safely cross over South Reserve Street, one of Missoula’s busiest streets.

After completing a feasibility study of various crossing alternatives, the Missoula Redevelopment Agency selected DJ&A as the engineer to design the bridge along the 50-mile Bitterroot Trail, which stretches from downtown Missoula to Hamilton.

The bridge main span superstructure is a steel arch bicycle/pedestrian bridge. It is 707-feet long from ramp landing to ramp landing, with a 190-foot main superstructure span over South Reserve Street. In addition to the main superstructure span, four (4) additional bridge structures were designed at the ramps to allow for business approach accesses below the crossing ramps.

With over nine different project stakeholders, weekly coordination meetings were held and problems were solved quickly to meet the project’s aggressive schedule. In addition to preparing the complete design and project bid package, the DJ&A Team provided construction staking and construction engineering support services.

Value Added

In addition to accommodating a variety of users, great care was taken to address long-term operations and maintenance of the bridge.  The bridge features lightweight FRP deck panels with integrated carbon-fiber heating elements to heat the surface of the bridge deck and eliminate maintenance costs associated with snow and ice removal, the first such application in the country.  Other low-maintenance items include a weathered steel superstructure and LED lighting to accent the bridge’s architectural features while providing safe passage at all-hours.
