SAN ANTONIO — Several main lanes of eastbound Interstate 10, along with De Zavala Road under the highway, will close this weekend as part of a construction project.

The work also will require more than a year of other closures in the area.

Starting at 8:30 p.m. Friday, all but one lane of eastbound I-10 from near Huebner Road to UTSA Boulevard will close. The lanes will reopen fairly quickly, at 5 a.m. Saturday, according to a Texas Department of Transportation road project blog.

De Zavala under I-10 will close to all vehicle, foot and bicycle traffic, also starting at 8:30 p.m. Friday. But De Zavala won't reopen until 5 a.m. Monday.

TxDOT advises motorists to avoid the area, but drivers can use the access roads and then turn around, either at UTSA Boulevard or Fredericksburg Road, depending on which direction they are headed.

Those are the short-term closures.

But also starting Friday night, the turnarounds under I-10 at De Zavala will close for a year.

In addition, starting Saturday morning, the eastbound and westbound main lanes of I-10 between Huebner and UTSA Boulevard will be reduced to three, 11-foot lanes for the next year. Currently, the lanes are 12 feet wide or more, and there are auxiliary lanes so drivers can merge more easily with traffic. Those lanes will be eliminated for the year.

The closures will allow contractor Webber Construction to eliminate part of the overpass at De Zavala and reconstruct it so the structure is taller, wider and longer.

The work is part of an ongoing project to widen I-10 between Huebner and Loop 1604, a $44 million project, said TxDOT San Antonio spokesman Josh Donat.

Webber took over the work after the previous contractor, Ballenger Construction Co., defaulted on the project and filed for Chapter 11 bankruptcy.
