Construction crews will be working to remove a concrete coating on the MoPac bridges at the 35th Street overpass. The work is expected to occur between 5pm and 5am on Sunday 7/27 with dual lane closures in the northbound direction and 9pm and 5am each night Monday through Thursday with dual lane closures in the northbound direction each night. Between July 27th and August 7th the work will be occuring adjacent to the Union Pacific railroad track on several nights. Union Pacific will require deployment of a train flagger for safety. Because workers will be in close proximity to the track, passing trains will be sounding their horns during the overnight hours. This horn noise could be disruptive to residents living nearby.
