BELLEVUE – Drivers are urged to plan ahead today to help reduce congestion and travel delays during the weekend-long closures of northbound Interstate 405 through Bellevue and the ramp from northbound State Route 167 to northbound I-405 in Renton.
“We need help from drivers again today to keep traffic moving as people head out to the Mariners game, go to work or simply enjoy the last day of the sunny weekend,” said WSDOT’s Northwest Region Administrator Lorena Eng. “We understand weekend road closures are inconvenient for drivers, but planning ahead can make them less stressful.”
As predicted, drivers around the greater Seattle-Bellevue area experienced longer than normal travel times on Saturday, especially on northbound I-5 heading into Seattle. The backups began in the late morning and continued through the early evening. Drivers also experienced slowdowns on northbound I-405 approaching Southeast Eighth Street in Bellevue and northbound SR 167 approaching I-405 in Renton.
Surface streets in Bellevue such as Bellevue Way, 116th Avenue Northeast, 148th Avenue Northeast and Northeast Eighth Street also saw heavier than normal traffic.
Beginning at 10 p.m. Friday, Aug. 9, all northbound lanes of I-405 between Southeast Eighth Street and State Route 520 were closed for concrete panel replacement work. The ramp from SR 167 to northbound I-405 also closed to decommission a failing metal drainage pipe and install a new rubberized pipe.
Drivers can expect more congestion on Sunday on regional highways such as I-5, I-405, SR 167 and local streets in Bellevue. WSDOT urges drivers to plan ahead and take five minutes to check WSDOT’s online travel resources.
Weekend construction progress
On I-405, crews from Atkinson Construction have removed more than 400 cracked and failing concrete panels. They are currently pouring new concrete for all new panels in the two right lanes between Southeast Eighth and Main streets in Bellevue. Crews are on schedule to finish the concrete work Sunday afternoon so the concrete can harden for at least 10 hours before new paint stripes are placed between the lanes. The panel replacement is important maintenance and preservation work that extends the life of this important commuter and freight corridor. Crews plan to begin reopening I-405 by 4 a.m. Monday with all lanes open by 5 a.m.
On SR 167, contractor crews from Active Construction completed pumping concrete into and around a 600-foot-long metal drainage pipe under the ramp from northbound SR 167 to northbound I-405. The pipe was filled with debris and collapsing, increasing the risk of flooding that could force an emergency closure of the ramp. The crew is now digging a trench more than 600 feet long to install a new rubberized pipe under the shoulder. The new pipe significantly reduces the flooding risk. The crew is on schedule to reopen the ramp by 5 a.m. Monday, Aug. 12.

Keeping traffic moving

Downtown Bellevue remains for business with several alternate routes available.
Incident Response Teams are on duty to clear incidents and stalled vehicles that worsen backups.
The I-5 and I-90 express lanes hours of operation have been adjusted to accommodate weekend traffic.
To reduce congestion, WSDOT is counting on drivers to:
• Delay or eliminate discretionary trips
• Travel before 10 a.m. or after 7 p.m.
• Allow at least one hour of extra time to reach destinations
• Know detour routes before driving
