Tex-Dot is starting a major project as part of the widening of I-10 in Jefferson County, west of Beaumont. Starting today, crews will begin demolishing the main lanes of the interstate at Hildebrandt Bayou to construct new bridges. The U-turn at Hildebrandt will be closed. Starting tomorrow, the I-10 Frontage Road from Walden Road to Hildebrandt Bayou will be two-way traffic. This is anticipated to be two-way traffic until the fall of next year.
