Winona’s interstate bridge will be shut down to traffic Friday — but not for long.
Crews plan to stop traffic at 10 a.m. for 15 minutes or so, as they hang a wire over the highway on Latsch Island for temporary lighting. Traffic will resume once the wire is strung and secured.
In related bridge work this week, traffic will be delayed on Thursday because of a routine inspection. The work is expected to take place from 8:30 a.m. to 3 p.m., with the potential for additional inspection work on Friday.
Traffic on the bridge will be reduced to one lane and controlled by flaggers during the inspection process. The use of a snooper is required, so motorists can expect short delays in their travels across the bridge.
The work is part of the final design phase for the rehabilitation work on the current bridge. The field visit by the final design team and the contractor is occurring so they can look at the scope of the work to ensure they have fully reviewed and understand the challenges and risks.
“This inspection work will help ensure our project team is able to deliver a high quality rehabilitation of the through truss, which is an important historical element of the existing bridge,” said Terry Ward, MnDOT’s Winona Bridge project manager.
The teams will be using one snooper, as well as two other lifts. The snooper is a special lift that allows inspectors to get under the bridge using the jointed arm of the device.
Finally, one block of West Fourth Street between Huff Street and Winona Street will be closed for 30 days beginning July 20, weather permitting. The detour will allow for the reconstruction of Fourth Street between Hwy. 43 and Huff Street. After this section of Fourth Street reopens, a new permanent traffic signal system at the Fourth and Huff intersection will be installed and become operational. Additionally, the block on West Fourth Street will be permanently posted as no parking.
Work continues to stay on schedule for the construction of the new interstate bridge, with plans to open the new bridge in late 2016 and begin rehabilitation work on the existing span the following year.
