A change is in store for northbound I-5 travelers exiting to westbound SR 516/Kent-Des Moines Road, the Washington Department of Transportation (WSDOT) announced Monday, Aug. 8, 2022.

At approximately 3:30 a.m. this Tuesday, Aug. 9, drivers will begin using a single off-ramp that exits to both eastbound and westbound SR 516.

For many years, the exits to each direction of SR 516 had separate off-ramps.

Northbound I-5 to SR 516 ramp change information

- The current exit to westbound SR 516 will permanently close at 7 p.m. Monday, Aug. 8.
- The existing ramp to eastbound SR 516 will close at 9:30 p.m. Monday, Aug. 8 and reopen at 3:30 a.m. Tuesday, Aug. 9, serving drivers headed to eastbound or westbound SR 516.
- The remaining off-ramp exit will be renamed exit 149.

Temporary adjustments to roadway signs will alert travelers to the change and will be in place until new roadway signs are installed. The existing traffic signals at the off-ramp’s intersection with SR 516 will be adjusted to accommodate traffic changes.

The Washington State Department of Transportation is closing this off-ramp as part of a planned reconfiguration of the I-5/SR 516 interchange, which includes the extension of Veterans Drive under I-5 and additional roadway and multi-modal improvements as part of the SR 509 Completion Project.
