The northbound exit ramp from Interstate 35 to Forum Parkway in the Live Oak-Selma area will close Tuesday night, and remain closed for the next six months.
The ramp is being replaced with a new braided-style ramp that is designed to separate competing lanes of traffic.
Traffic to Forum Parkway will be bridged over traffic entering northbound I-35 from Loop 1604.
"The end result will benefit drivers in the area and the businesses they are trying to reach," said TxDOT spokesman Josh Donat. "When we're finished, we'll have a safer, more reliable route for traffic heading in both directions -- to Forum Parkway as well as to I-35. In the meantime, drivers should be aware of the ramp closure and look for alternate routes."
But for now, drivers say the problem area will get even more difficult to navigate.
"I have to turn the news on every morning just to see what traffic is. Then it kind of tells me when I should leave the house," Mindy Webber said.
Traffic headed to Forum Parkway may use the Olympia Parkway exit, cross over I-35, and approach Forum Parkway from the south as a detour.
Another viable route involves exiting I-35 at Pat Booker and taking the turnaround under Loop 1604. More than a half-dozen entry points to the Forum line the west-bound frontage road of Loop 1604.
"We've worked closely with the property managers at the Forum," Donat said. "We all feel the Pat Booker route is the preferred detour."
Traffic accessing Forum Parkway from southbound I-35 will not be affected. Traffic entering northbound I-35 from Loop 1604 will not be affected, either.
According to TxDOT, work is part of a year-long effort to address congestion and maintain the safety of one of the busiest highway corridors in the San Antonio metropolitan area.
"We've worked closely with the property managers at The Forum," Donat said. "We all feel the Pat Booker route is the preferred detour," said driver Jennifer Chavarria.
