Beginning Friday, traffic on State Highway 201, from Reese Creek Road to Ivy Mountain Road, will shift lanes until project completion scheduled for spring 2013.
All westbound traffic will use the outer westbound lane, and eastbound traffic will use the outer eastbound lane.
The two interior lanes will be closed.
Left-turn lanes will be open at Bunny Trail, Maxdale Road and the Texas A&M University-Central Texas main and west entrances.
The city asks motorists to use caution while driving in the area and pay particular attention to signage. These closures are part of the State Highway 195-State Highway 201 overpass project, which is set for completion next spring.
