The New I-64


Construction Zone

This web site provides information for the I-64 reconstruction project, from just west of Spoede Road to just east of Kingshighway Boulevard. If you need information for other roadways or construction projects in the St. Louis region, please view the St. Louis Area MoDOT Weekly Road Construction Report.

Construction to rebuild I-64/US40 between Spoede Road and Kingshighway Boulevard began in March 2007.  All lanes of I-64/US40 between Ballas Road and I-170 (the west half of the project) closed in both directions on January 2, 2008, and reopened on December 15, 2008.  That same day, all lanes of I-64/US40 between I-170 and Kingshighway Boulevard (the east half of the project) closed.  The highway completely reopened to traffic on December 7, 2009.

Now that I-64/US40 has reopened:

  • At I-64 and I-270, all movements to and from north and southbound I-270 are open and you can access both directions of I-64/US40 from Ballas Road.

  • There is a direct connection between I-64/US40 and I-170.

    • Traveling east on I-64/US40, three lanes continue eastbound to downtown, one lane exits at Brentwood Boulevard and Hanley Road and one lane merges with northbound I-170 via a flyover ramp.

    • Traveling west on I-64/US40 from downtown, three lanes continue westbound, one lane exits at Hanley Road and Brentwood Boulevard and one lane merges with northbound I-170 via a flyover ramp.

    • Traveling southbound on I-170, one lane exits to eastbound I-64/US40 via a flyover ramp, one lane exits to westbound I-64/US40 via a flyover ramp, and two lanes exit to Eager Road, with one to northbound Brentwood Boulevard only.
