The first new flyover ramp in Federal Way opens today.
The ramp connects westbound state Route 18 to southbound Interstate 5. A second flyover ramp connecting eastbound SR 18 and northbound I-5 is slated to open July 23.
A ribbon-cutting ceremony will be held at 10 a.m. The state Department of Transportation said a semitruck will be the first vehicle to use the new ramp, which will then open to all drivers.
The ramps, which are opening six months ahead of schedule, are part of a $112 million project to improve the traffic and safety at the interchange.
