Construction workers are picking up the pace widening Interstate -405 and southbound SR 167 in Renton and Tukwila.

July 11-13, during the night and early morning hours, crews may close a lane in each direction on I-405 between SR 167 and I-5 for electrical and barrier work.

July 14-17, during the night and early morning hours, crews may close up to two lanes on southbound SR 167 between I-405 and South 180th Street while crews continue to build the foundation for a new southbound lane.

July 15, during the night and early morning hours, crews may close two lanes on northbound I-405 between SR 167 and I-5 for electrical work.

July 17, during the night and early morning hours, crews may close two lanes of southbound I-405 between I-5 and SR 167 for electrical work.

Specific closure details will be posted on WSDOT’s I-405 construction updates Web site by noon on Friday: http://wsdot.wa.gov/projects/i405/conupdates

On July 12, during the early morning hours, Puget Sound Energy crews will perform a rolling slowdown on I-405 between Northeast 44th Street and I-5 and close one lane on northbound I-405 between SR 515 and SR 169 to give PSE crews time to cut a deactivated power line and then relocate a new power line above I-405.

June 12-13, during the daytime hours, PSE crews will have a truck on the southbound shoulder of I-405 between SR 167 and SR 169 with its arm extended over the median of I-405 to create a protective barrier while crews complete relocation of power lines. While no lanes on I-405 will be closed, the work may pose a visual distraction for drivers.The power lines are being relocated in preparation for the I-405/I-5 to SR 169 Stage 2 – Widening and SR 515 Interchange project that is scheduled to begin construction late 2008 or early 2009.
