SAN ANTONIO – Sundt Construction is closing all main lanes of Interstate 10 at Ralph Fair Road this weekend, beginning 7 a.m. on Saturday, Sept. 20.
Sundt is also closing Ralph Fair Road between Old Fredericksburg Road and I-10.
The closures will allow Sundt to set nine bridge support beams -- each one 165 feet long -- that will make up the backbone of a new section of the Ralph Fair Road overpass.
Sundt is half a year into a year-and-a-half project to rebuild the overpass, expanding the bridge in the process.
Those beams will leave the fabrication plant at 7 a.m. (they are required to wait for daybreak to begin their trip) and use Loop 1604, U.S. Hwy 281, Texas Highway 46 and FM 3351 to reach the work zone.
Job bosses are expecting the trip to take about an hour and a half -- about as long as it will take traffic crews to shut down the road. Bridge crews hope to start setting the first beam around 9 a.m.
Those driving along the haul route -- Loop 1604, U.S. 281, Hwy 46 and FM 3351 -- during the morning hours may experience some delay. All trucks should be clear of the route and at the project site by noon.
Bridge crews will be setting beams through the day. Project bosses expect to finish up work by Sunday morning, but may need more time.
At the latest, main lanes will reopen by Monday morning at 5 a.m. During that time, motorists are encouraged to try alternate routes (such as U.S. Hwy 281 and Hwy 46 to get from Boerne to San Antonio) or plan for about an extra hour to their travel plans.
Area residents ready for construction to finish
Trey Lynn, a Boerne resident, said he heard about the closures and is planning on staying home this weekend to avoid the big traffic mess.
"This intersection has already been bad, but now it's really going to be bad because there are so many people trying to do the turnaround here and people going to I-10, going to Boerne into town. said Lynn. "It's going to be a nightmare for a while. Hopefully, it will get fixed soon."
