Month-long ramp closures at I-84 Simco Road Interchange

Girders being set on the bridge

The westbound on- and off-ramps at the I-84 Simco Road Interchange (Exit 74) will close tomorrow morning as crews continue rebuilding the interchange.

The closure is expected to last more than one month, with drivers detoured to the nearest interchange to the west at Exit 71 to access the freeway. The eastbound on- and off-ramps at Exit 74 will remain open.

Construction began in July to rebuild the bridge over I-84, which was built in 1959. While being reconstructed in place, the bridge will have one lane open so that motorists can cross over the freeway. Work is expected to be complete next summer.

Travelers are reminded to know before they go and check for traffic impacts.
