ROUND ROCK —The Texas Department of Transportation is celebrating the completion of two important projects in Round Rock. TxDOT was joined today by U.S. Representative John Carter’s office, Williamson County Commissioner Terry Cook, and Round Rock Mayor Craig Morgan to cut the ribbon on more than $20 million in mobility improvements along I-35.

The $9.2 million I-35 from RM 1431 to FM 3406 ramp reversal project along the southbound I-35 frontage road reduces vehicle weaving and improves frontage road operations by adding an extended entrance and exit lane. The $12.4 million I-35 at FM 3406 bridge reconstruction project includes a new, expanded bridge with two new U-turn bridges in each direction and dedicated left-turn lanes.

Williamson County Commissioner Cook expressed her excitement for the completed projects with a rap song. “By end of June, traffic’s flowing – gone massive backups, east-west smoking,” sang Cook.

In addition to improved vehicle mobility, pedestrians and bicyclists can now travel from RM 1431 to FM 3406 on a new 10-foot shared-use path and connect to FM 3406 and other destinations using improved sidewalks and pedestrian beacons.

“These new bicycle and pedestrian enhancements have greatly improved safety for all modes of transportation,” said City of Round Rock Mayor Craig Morgan. “I drive this route often, and I am excited to see how this project continues to improve mobility in this area.”

Both projects were funded by TxDOT and completed on time and on budget. The contractor for the I-35 from RM 1431 to FM 3406 (southbound) project was Dan Williams Company, and the contractor for the I-35 at FM 3406 project was Flatiron.

“Thanks to the hard work of the project team, the new FM 3406 bridge was completed two months ahead of schedule,” said TxDOT District Engineer Terry McCoy. “We thank drivers for their patience while these much needed improvements were constructed.”

These are the fifth and sixth projects completed as part of the Mobility35 Program. In 2011, TxDOT developed the program to improve safety and mobility along I-35 through Williamson, Travis, and Hays counties.
