More than 30 percent of people who drive on the 183-A tollway's anomalous toll-tag-only section are doing so illegally, an abnormally high violation rate that has the road's operator pondering alternatives to the confusing setup.
The Central Texas Regional Mobility Authority has asked Vollmer Associates, its traffic and revenue consultant, to analyze what might result from several scenarios, including continuing under the current arrangement. The authority expects to have that information within a few months and could consider making changes in the fall.
Tracking 183-A tolls
In June, the first month when all cars on 183-A were subject to tolls (albeit at a reduced rate for toll tag users), the road averaged 55,850 toll transactions a day. However, more than 11,000 of those times — about 20 percent — the driver did not pay for the privilege, many at the toll-tag-only toll gantries near Lakeline Boulevard.
