Mirror staff reports:

Crews will close several lanes of northbound I-5 for nightly pavement repairs between Federal Way and Kent.

From 9 p.m. to 5 a.m. the week of Feb. 4, crews will close up to three out of five lanes from South 308th Street to South 260th Street.

The crews have finished concrete panel replacement work and will grind down three miles of rutted concrete in the northbound direction of I-5, according to the Washington State Department of Transportation (WSDOT).

The work is expected to last through the spring. The end result will be a smoother and quieter ride for all drivers, WSDOT reports. The $6.4 million project, which began in April 2012, includes a new guardrail, high-visibility striping and more reflective signs.

According to WSDOT, Interstate 5 through King County is nearly 50 years old and is used by more than 250,000 cars, trucks, semi-trucks, buses, and oversized vehicles every day. Roads that are in good shape last longer and experience fewer collisions, which means fewer unexpected lane closures, according to WSDOT.
