CORPUS CHRISTI, Texas — There only being one way on and off Padre Island may soon be a thing of the past.

For years, the Metropolitan Planning Organization has studied ways to connect the Crosstown Expressway and Park Road 22. At last, they've narrowed down potential routes thanks to a study that was completed in 2017.

While plans for the Regional Parkway are still preliminary, the determination to build is completely underway.

MPO Director of Transportation Planning Robert MacDonald said now that Corpus Christi has added the project to their long-term list, they can proceed with an environmental study as mandated by the National Environmental Policy Act.

After that, the MPO has to find funding for construction.

MacDonald said the route they choose will depend on studies and the amount of money they receive.

"We have to do the environmental clearance of it then get into design, then you get into building it over the next 10 or 20 years or if we find money, sooner," MacDonald said.

MacDonald said the project's cost is estimated at $350-400 million. Yet, as time passes, the cost could change.

"All along the way we keep re-estimating where we think the money can come from, how much the money will be, because the value of this project will change over time," MacDonald said.

Then, when funding is in place, MacDonald said they will choose the best route to connect 286 and Park Road 22.

"We start to refine where that's going to be, what the roadway's going to be, how do you accomodate transit and bicycle, the whole network has to fit into the corridor," MacDonald said.

There are several routes that the MPO have identified and everything depends on the funding that they can recieve.
