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 Highway 46 (Bandera Road). 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. Check back frequently and follow the City of Boerne on Facebook and Twitter for the latest information. Learn about current and upcoming road closures below.

Current Closures

School Street at I-10 West Frontage Road

The next stage of construction at I-10 and Highway 46 will require the complete closure and reconstruction of the intersection of South School Street at the existing I-10 westbound frontage road.

This phase of the project remained under construction as of mid-December. Please note: the new I-10 West entrance ramp from Highway 46 is now open. Access to businesses between School Street and Highway 46 (Days Inn, Taco Bell/Exxon) are possible via the frontage road from I-10. South School Street reopened in the fall. 

Eastbound I-10 Frontage Road

The existing Eastbound I-10 Frontage Road will be closed from Menger Springs to Highway 87 (Main Street). The road remained closed and under construction as of mid-December.

During the closure, traffic on the Eastbound I-10 Frontage Road will be detoured onto I-10 via the new entrance ramp past Menger Springs and can exit back onto the Frontage Road via Exit 543 to Scenic Loop Road.

This closure is being done to allow TxDOT’s contractor to construct the new frontage road and the approach work to the Highway 87 bridge.
