I-10 Construction News

Project Overview

Work is currently underway on TxDOT's I-10 Kendall Extension project, causing a significant impact on traffic in and around the City of Boerne. As part of the project, TxDOT is replacing two overpass bridges across I-10 in Boerne – one at Main Street and one at Bandera Road/Highway 46. Improvements are also being made to the access roads, including conversion to one-way traffic. The city will utilize this webpage to provide updates as we receive them from TxDOT and its contractors.

As work on these projects progresses, TxDOT will announce closures that will impact the flow of traffic in and around Boerne. Please be aware that any scheduled closures are subject to change.

Current Closures

Eastbound I-10 Frontage Road at Highway 46 (Bandera Road)

TxDOT contractors have closed the I-10 Eastbound Frontage Road from Highway 46. This closure started in mid-September and is expected to last six weeks.

Once this closure is complete, crews will shift traffic onto the newly constructed Highway 46 bridge over I-10 and then demolish the old bridge.

Highway 46 Traffic

  • During this closure, traffic on Highway 46 will still be allowed to travel over I-10 via the old bridge. However, drivers will not be able to access the eastbound frontage road from Highway 46. Traffic on Highway 46 in front of Home Depot is continuing to be shifted onto temporary pavement. One lane of traffic will be open in each direction.
  • Johns Road will be the primary detour route for access from Highway 46 to I-10 East toward San Antonio. This means drivers trying to access I-10 East from Highway 46 will first need to take I-10 West, take Exit 539 to Johns Road, cross over I-10 via the Johns Road bridge, and then access I-10 East.
  • The Johns Road detour also gives drivers access to the new Eastbound U.S. 87 Exit ramp under the Highway 46 bridge. The new exit ramp provides access to Grand Boulevard, Menger Springs Road, and the hospital.
  • Drivers trying to get into San Antonio, they may also utilize several city streets (Norris Avenue, Herff Road and Christus Parkway) to get onto the frontage road south of the I-10/Highway 46 intersection and turning around on the new U-turn bridge, which remains open. The temporary on-ramp south of the intersection remains open for easier access to I-10.

Westbound I-10 Traffic

  • Westbound I-10 traffic will utilize the new Highway 46 turnaround bridge to access eastbound frontage road local business, Grand Boulevard, Menger Springs Road, and the hospital.

Upper Balcones Road

  • Drivers will not be able to access the eastbound frontage road from Upper Balcones Road. Upper Balcones Road will remain open to access local businesses.

Local Business Access

  • Access to Home Depot, Whataburger, and Chili’s will be possible from Highway 46 in front of Home Depot. Access to Starbucks and Boerne Church of Christ will be possible from Upper Balcones Road via Coughran Road. Access to business along the Eastbound Frontage Road (including the Hampton Inn, Quick Oil Change, and Brake Check) will be possible by using the new Highway 46 turnaround bridge from the westbound access road.
