Weather permitting, work is scheduled to begin as early as next week on the bridge replacement and interchange improvement project located on Missouri Route 19 over Interstate 70 in Montgomery County at mile marker 175, Hermann exit.
This project will replace the bridge over I70 and include interchange improvements with two new roundabouts, enhancing traffic flow at this location to accommodate current and future area needs. The new bridge will be constructed just west and adjacent to the existing bridge. Input was received from area residents and stakeholders during a public meeting and comment period, held in February of 2020. “Based on feedback from the public meeting, the design for the new interchange will be different from the existing interchange and will include two roundabouts one on each side of the bridge to decrease congestion and increase traffic flow. These roundabouts are larger in comparison to other local roundabouts and specifically designed to accommodate large trucks and farm machinery that utilize this interchange.” explained Missouri Department of Transportation Area Engineer Jeff Niemeyer.
During the course of construction, each roundabout will be built one half at a time to minimize traffic impacts. No significant closures are scheduled until the Spring/Summer of 2023, however, drivers may experience minor detours to access area businesses at the interchange. Overall construction will include six stages with completion anticipated in the Winter of 2023. Within the initial phase of the project, work will begin on the substructure of the new bridge in addition to grading, tree removals, and installation of temporary pavement at various locations needed for managing traffic in later stages of construction. There will be no substantial traffic impacts on Missouri Route 19, I-70 or the I-70 ramps during this stage of work.
“The entire area of the interchange will be an active work zone over the next year. We would like to remind drivers to please slow down, obey all signs and eliminate distractions while driving. The safety of the traveling public and our workers is our top priority,” stated Niemeyer. Signs and message boards will be in place to alert motorists, as schedule changes occur. MoDOT will alert the public about the project through signs, news releases and social media.
