FROM STAFF REPORTS
AUSTIN — The Texas Department of Transportation has completed its reconstruction of three commuter-choked intersections along U.S. 290 West in southwestern Austin.
Two of intersections — U.S. 290 at Texas 71 and U.S. 290 at William Cannon Drive — have been redesigned as “continuous flow intersections” like those completed last year at two Interstate 35 intersections in San Marcos. Continuous flow intersections increase roadway capacity by allowing left-turning traffic and through-traffic to pass through an intersection simultaneously. Alterations to the U.S. 290-Joe Tanner Lane intersection include restricting left-turning traffic.
The project cost $6.5 million, TxDOT officials said.
“Travis County and the city of Austin partnered with us in the funding of these interim improvements that will bring some traffic relief to the area,” said Victor Vargas, TxDOT’s area engineer for southern Travis and Hays counties.
The Texas 71, William Cannon Drive and Joe Tanner Lane intersections comprised the second phase of a package of stop-gap congestion relief measures called the “U.S. 290 Oak Hill Interim Intersection Improvements” project.
The $4.6 million first phase — new left-turn lanes at three locations and a center-turn lane on U.S. 290 between RM 1826 and Convict Hill Road — was completed in September.
