Interstate 10 highway sign

Project Overview

Work is substantially complete on TxDOT's I-10 Kendall Extension project. As part of the project, TxDOT  replaced two overpass bridges across I-10 in Boerne – one at Main Street and one at Highway 46 (Bandera Road). Improvements were also 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. Learn about current and upcoming road closures below.

Ongoing Projects

There are various small projects being done along I-10. In general, construction times are projected to occur between 9 a.m. and 3 p.m. and might result in temporary lane/ramp closures. As always, follow all signage and law enforcement direction around the construction zones.
