I-5 Metro Air Parkway Interchange

Project Description

This new interchange will extend Metro Air Parkway south to and over Interstate 5. 

The interchange will be Metro Air Park’s front door.  Situated near I-5, Highway 99, and Highway 70, Metro Air Parkway is a natural jumping off point for transporting of goods. The I-5 interchange will help foster that transportation access to Metro Air Park.

Project Cost:

$17.9 million

Road Closure Information

Southbound Highway 99 To Northbound I5 Connector  

SacDOT will conduct an overnight closure of the southbound Highway 99 to northbound I5 connector near the Metro Air Parkway interchange construction project.  Construction crews will close the connector on Saturday, June 12, at 10 p.m., and reopen Sunday, June 13, at 6 a.m.  During the closure, vehicles will be detoured along the following route: 

SATURDAY, June 12, 2021 10 pm – 6 am

Bayou Way

Bayou Way (the frontage road next to I-5 near the airport) from Tarboro Lane to Power Line Road until November 2020.  The first phase work along Bayou is to remove and rebuild water lines that feed the Airport.  The second phase will be the construction of the interchange and overpass on I-5 which will also require construction crews to continue working on Bayou Way.
