  1. Convict Hill Road and Escarpment Boulevard intersection, signal improvements


The first leg of work is complete to improve safety and mobility for Convict Hill Road, which was restriped to include three lanes and flashing yellow left-turn signals. Similar turn signals were also added for the existing left-turn lanes on Escarpment Boulevard. The project is estimated to cost $50,000 and will be paid for through the city's Quarter Cent Fund.

2. Hwy. 290 widening


Work has begun on a Texas Department of Transportation project to widen the portion of Hwy. 290 between Circle Drive and El Rey Boulevard. The project will add a continuous center turn lane, increasing the number of lanes from four to five, and will add and pave shoulders along the roadway. The project is projected to cost $1.9 million, according to TxDOT.

3. Oak Hill Parkway


A study is underway to analyze the potential traffic noise impact from the Oak Hill Parkway build options. A few design changes have also been made, including the proposed addition of non-turn lanes in each direction on Hwy. 290 from Hwy. 71 to west of FM 1826. The proposed addition of bus turnouts along Hwy. 290 and Hwy. 71 frontage roads, a possible width reduction of Hwy. 71, and the proposed addition of short retaining walls to protect some properties and trees are also among the changes.

4. Slaughter Creek overpass replacement


TxDOT began work May 2016 on a project to replace the Slaughter Creek overpass at I-35 and build a new southbound-to-northbound U-turn bridge. The contractor is finishing the southbound retaining wall and is working on the southbound frontage road reconstruction as well as installing railing on the bridge.
