TX183A tollroad in northwest of Austin area allows 75mph

July 12, 2012

75mph speed limit signs should be appearing in early August on the Central Texas Regional Mobility Authority's 183A tollroad that leads to the suburbs in the northwest of Austin TX - Cedar Park and Leander.

A new state law allows higher speeds on modern expressway standard highways like 183A. The authority says a speed study determined 75mph as the appropriate speed limit. It was previously 70mph.

In Texas safe driver behavior - as measured by the speed of the 85th percentile of drivers - is generally used to set posted limits.
