DJ&A provided engineering, surveying, and construction management support for two neighboring redevelopment projects within the Johnson Triangle, a blighted parcel in the heart of Missoula, Montana being transformed into a city park and trail connection.

At the 4.5-acre future park site, DJ&A was responsible for design of irrigation and potable water systems, a pavilion shelter, sports fields, playground areas, garden spaces, trail and sidewalk, roadway improvements, and a bus stop.  The new park development included more than 1,500 lineal feet of accessible trails and sidewalks.  The MRL Park site is located within an under served area lacking open public park space.  The park design includes community garden plots, aiding in building community involvement through agriculture by growing food with and for people with low incomes.

On the adjacent trail project, DJ&A designed the last remaining segment of the Bitterroot Trail (2,200 feet) along an active railroad corridor.  This connection laid the ‘golden spike’ in the Bitterroot Trail networks which connects Downtown Missoula to Hamilton, MT.   This project also included the design and construction of Montana’s very first bicycle activated diagonal intersection crossing, equipped with bicycle triggered inductive loops and bicycle signal heads.

Key Services

  • Conducted topographic survey and mapping of entire parcel, including railroad tracks, building boundaries, curb and sidewalks, and other existing features
  • Engineered path alignment, grade, and cross section features to follow all State and Federal ADA and PROWAG requirements
  • Prepared storm drainage engineering report
  • Surveyed right-of-way of the park site and creation of encroachment exhibits for the trail segment
  • Designed Montana’s very first bicycle activated diagonal intersection crossing
  • Procured trail corridor lease
  • Developed biddable construction documents

Value Added

DJ&A’s design included Montana’s first bicycle-only diagonal crossing, which includes bicycle signal heads, inductive loops with bicycle wait boxes, and other crossing upgrades.

It was a pleasure working with you (Kyle Gauthier, DJ&A Engineer assigned to project) from initial design through the completion of construction.  Thanks to the good work from you and your team at DJ&A, the project was completed well under budget!  I look forward to teaming up with DJ&A again on future MRA projects.
