HOUSTON -

Hobby Airport is making room for its new parking garage.

Beginning Tuesday, the ecopark 1 economy parking lot at Hobby Airport will permanently close in order to make room for both roadway improvements and a new multilevel parking garage.

The improvements are taking place in anticipation of the arrival of international air service at Hobby Airport.

A new five-gate terminal facility is being constructed by Southwest Airlines and is slated for completion in late 2015.

According to the Houston Airport System, the arrival of regional international air service is expected to generate an additional 1 million passengers on an annual basis.

The new parking garage is expected to bring an additional 3,000 spaces to the Hobby Airport parking inventory.

With the closure of ecopark 1, passengers are now being directed to use ecopark 2, which is located to the east and northeast of the covered garage.

All vehicles located at ecopark 1 past March 28 will be relocated to ecopark 2.
