Construction for Carroll ISD's new music center may cause some traffic delays as the new school year begins Aug. 19. The music center is being built on the site of Carroll Senior High School, located at the intersection of Southlake Boulevard and South Peytonville Avenue. Drivers heading southbound along South Peytonville will not be able to turn into the school at its north driveway, and the turning lane has closed, Southlake Public Works Director Rob Cohen said at the Aug. 6 City Council meeting. Those trying to exit from the campus will still be able to go out at that driveway.  The southern driveway will still be open for entry, and its turn lane will be open, but there may still be delays in that area, Cohen said.  “It’s going to be a very tight area to work in for a good while,” he said.  Drivers should also be aware of changes on North White Chapel Boulevard, which is adjacent to Carroll High School. Construction crews have been working on North White Chapel from Highland Street to SH 114 as part of Phase 1 of the project, Cohen said. But the project timeline indicates drivers will be able to travel north and south with one lane in each direction. The single-lane roundabout at Highland will also be open, he said. The city is focused on a strong communication campaign to provide updates on various road projects. Residents can visit the Southlake Mobility Facebook page or www.connectsouthlake.com.
