Three flyovers will be constructed between the two highways from northbound SH 130 to westbound Toll 290, from southbound SH 130 to westbound Toll 290 and from eastbound Toll 290 to southbound SH 130. The project will be completed in 2021.
The Central Texas Regional Mobility Authority and the Texas Department of Transportation are partnering on the project with the Mobility Authority overseeing construction. TxDOT is providing $41.1 million toward the total cost of $127 million to finance the eastbound Toll 290 to southbound SH 130 flyover, which will not be tolled.
The interchange has one existing flyover from eastbound Toll 290 to northbound SH 130, which is also nontolled.
Toll 290 opened in 2014 and a $3 million interim improvement project was finished in 2016 to widen the southbound SH 130 frontage road at Toll 290 and add two right-turn lanes and two onramps to westbound Toll 290 from the SH 130 frontage road.
