Blanco Road Phase III

Bexar County is transforming a 2.2-mile segment of Blanco Road into a four-lane divided minor arterial with a raised median and turn lanes. This major roadway renovation, filed as Blanco Road Phase III, spans from Borgfeld Drive to the Bexar/Comal County line in San Antonio. The project is scheduled to finish in February 2028, with construction work beginning in October 2025. This expansion converts existing rural collector infrastructure into a high-capacity urban arterial to support traffic flow in the Avenida Guadalupe area.

The estimated cost for this renovation and alteration is $48,056,613.

The scope involves significant civil engineering work to expand the roadway capacity and improve safety through the addition of a raised median and dedicated turn lanes at specific locations.
