Troy Monroe, Assistant City Engineer, discussed a waiver of Missoula Municipal Code Chapter 9.30 Noise Control at the Orange Street Underpass. Approximately one year ago, the underpass was closed for soil borings. Phase Two of this Montana Department of Transportation (MDT) project will be a concrete study. The concrete testing will not affect the historic part of the underpass.
The contractor is required to complete the work at night, which is why a noise waiver is necessary. The work will begin on October 22, 2019. The underpass closure will only affect northbound vehicles so emergency traffic can pass through.
On October 7 and October 8, 2019, Montana Rail Link (MRL) completed emergency underpass repairs. Because time was of the essence, the noise waiver could not be obtained. City Council area representatives were notified of the repair, as was the Mayor's office.
Ownership of the underpass or the responsibility to maintain it is not clearly defined. It is a complicated structure with the railroad tracks and buildings on top of it. Ross Mollenhauer, Utility Project Manager, stated that MDT has the Orange Street Underpass on their five-year plan.
