AUSTIN – The existing bridge at I-35 and Ronald Reagan Boulevard will be replaced with two new bridges, one for eastbound traffic, the other for westbound. The project will realign Ronald Reagan Boulevard and connect CR 311 to the bridges. Each bridge will include one travel lane, a bike lane and a six-foot sidewalk. The $12.3 million project was awarded to Dan Williams Company. The Mobility35 program includes more than 40 projects designed to improve mobility and safety along I-35 through Williamson, Travis and Hays counties.

Another leg of US 290 East will become a four-lane divided highway in Lee County. The project will divide US 290 from the Bastrop County line to Navarro Street in Giddings. A grassy median with a cable barrier will separate new eastbound lanes from the westbound lanes along 7.5 miles of US 290. Inside and outside shoulders will also be added. The $28.3 million project was awarded to Big Creek Construction LTD. Work began earlier this year on a similar project on US 290 in the McDade area. A third project was awarded in December that will divide US 290 from FM 2104 to the Lee County line. Together, these projects will reconstruct US 290 East into a four-lane divided highway through the Austin District.

Passing lanes will be constructed along part of SH 29 in Llano County, from approximately 2.5 miles west of RM 1431 to 5 miles west of RM 1431. The project includes passing lanes and 10-foot shoulders. The $3.9 million contract was awarded to Acme Bridge Company Inc. This is Phase I of a four phase project that will include passing lanes, turn lanes and intersection improvements from RM 1431 to RM 2241.
