Planners conceived the parkway in the mid-1980s as the
East–West Parkway, an extension of the existing Wurzbach Road, to relieve traffic on
I-410. The road, estimated to cost $90 million, was approved by the
Texas Transportation Commission in 1988, to be built by the state but funded in part by the City of San Antonio. Construction began in mid-1994 on the section between Wetmore Road and Nacogdoches Road and opened in July 1996. The eastern portion of the roadway opened on August 26, 1999, allowing traffic to bypass I-410. The west section was opened on July 24, 2002; its fourth section opened on December 23, 2013. In September 2015, the central stretch of the parkway opened to traffic, effectively completing the project after 21 years. The
Alamo Regional Mobility Authority (RMA) conducted a
supplemental environmental assessment on the entire corridor from Lockhill–Selma Road to
I-35, emphasizing the segment that had not been constructed. The EA supplemented the EA completed several years prior to initial construction. The Alamo RMA considered three alternatives for the interchange with
US 281. The first alternative was a Wurzbach Parkway bridge over US 281 with no direct connection between the two highways, but with access via the highway's two
frontage roads (this option was chosen). The second option would have included an elevated
roundabout interchange to provide direct access between the highways. The final alternative would have involved main lane to main lane connector ramps from Wurzbach Parkway to US 281 and loop ramps for access from US 281 to Wurzbach Parkway. According to the
San Antonio Express-News, the Texas Transportation Commission reviewed the parkway expansion on November 19, 2009. The project was funded by proceeds from Proposition 12 bonds approved by voters in 2007, a package which was voted on by commissioners. Clay Smith, TxDOT's San Antonio District planning engineer, said the Wurzbach Parkway project would get $126 million under the bond-financing plan, enough for TxDOT to finish the three final segments left on the parkway. The expansion construction was completed in two phases: the first from Blanco Road to West Avenue and from Jones Maltsberger Road to Wetmore; the second between West Avenue and Jones Maltsberger. The parkway has no ramps that connect directly to I-35 to the east (only allowing drivers to use O'Connor Road that leads to the parkway) and no plans for Wurzbach Parkway to extend to I-10 to the west (only allowing drivers to use the Wurzbach Road exit to connect to the parkway).
Future TxDOT has also proposed improvements to the parkway's intersections at NW Military Highway and Lockhill-Selma Road. ==Major junctions==
