Impacts to Traffic

Lane closures are possible Monday through Sunday except on holidays or holiday weekends.  A wide load restriction for westbound loads over 12 ft. wide is in effect from 6:00 am to 6:00 pm.  The westbound Ryegrass Rest Area is closed for the month of October and possibly into November 2003, due to construction impacts.  The legal speed limit is reduced from 70 mph to 50 mph 24 hours a day in the westbound lanes, and during hours of work in the eastbound lanes.  Bicycles are detoured to the Old Vantage Highway.  For the 2004 construction season, westbound lanes will be detoured to eastbound lanes with two lanes westbound and one lane eastbound, separated by median barrier.
