Jackson Contractor Group, in coordination with the City of Missoula, will conduct subsurface investigation work along Higgins Avenue and nearby downtown streets Nov. 9-20, 2026, weather and conditions permitting. Crews will work on weekdays only.
Work overview
Crews will use a soft excavation process called potholing, or hydro excavation, to safely locate underground utilities and verify their depth and condition before construction begins on the Downtown Safety, Access and Mobility (SAM) project, anticipated to start in 2027. This preliminary work helps with final design coordination, reduces the potential for utility conflicts, and helps to minimize disruptions during future construction.
There may be temporary parking restrictions, sidewalk detours, or localized traffic impacts. Access to businesses will be maintained throughout the work, although minor adjustments to pedestrian and vehicle access may be necessary. Drivers may encounter temporary lane closures, parking restrictions and minor delays near active work areas. Traffic will continue moving through the area, and crews will maintain access for emergency vehicles and public transit.
