Over the course of construction there will be major activities that will impact the region. As those activities are scheduled, we will keep the community updated.

Temporary Traffic Shift Northbound US 183 at Loop 360 Exit

Crews have instituted a temporary traffic shift, lasting approximately 6 weeks to accommodate construction activities on the 183 North Mobility Project (schedule subject to change) for the exit ramp to Loop 360 from northbound US 183. During the shift, the right lane option to continue on northbound US 183 is closed, and drivers in the right lane must now exit to Loop 360.

Temporary Lane Reduction on Southbound MoPac Frontage Road

Beginning the week of 2/2/26 crews will be reducing the southbound MoPac frontage road down to one lane between US 183 and Steck Ave. for approximately 6 weeks (schedule subject to change). This work is part of the last phase of major activity in this area as the 183 North Mobility Project nears completion and crews will work as quickly as possible to reopen the lane.
