Due to a previous mudslide and ongoing repairs, only three lanes (out of four) will be open on northbound I-5 at Templin Highway. Heavy holiday traffic and possible delays are expected over the upcoming Labor Day weekend.

While this is an ongoing closure, all planned construction, maintenance and encroachment permit activities that could create delay for motorists are to be suspended over the upcoming Labor Day weekend. This would include the following period:

Beginning Friday, September 1 from 6 a.m. to 11:59 p.m. — and Sunday, September 3 at 11:59 p.m. through Tuesday, September 5 at 6 a.m.
