Use Lombard street as an alternate route. The above schedule is tentative and may vary by a day or two. The first Interstate 5 overpass structure raising will take place Tuesday, April 10 beginning at 10 p.m. The Lombard Overpass along with four other structures will be raised in order to meet federal height standards as part of the I-5 Preservation Project. During the structure raising, flaggers will control traffic on Lombard Street and the westbound loop ramp from I-5 northbound.
Motorists can expect twenty-minute delays.
In addition to Lombard Street, the Portland Boulevard Overpass, Ainsworth Street Overpass, Alberta Street Overpass and the Failing Street Pedestrian Bridge are the structures that will be raised this summer. No impact to I-5 traffic is anticipated. The walls are being placed between Ainsworth and Cook Streets on the east side of I-5, and between Ainsworth and Beech streets on the west side. Construction begins with the removal of shrubs and trees. This provides the necessary space to site and install the new soundwalls.
