AUSTIN, Texas — Drivers traveling through North Austin and Cedar Park are beginning to see noticeable changes along the U.S. 183 corridor as the 183 Mobility Project moves into its next phase. Construction crews have removed many of the orange barrels that once lined the roadway, making way for newly opened lanes and new toll infrastructure along the corridor. The project now includes one additional non-tolled lane in each direction, two express toll lanes, and a tolled connector ramp to MoPac.
