Project description: Photos courtesy Atkinson-CH2M Hill, A Joint Venture The flyover bridge will exit from the right-hand side of northbound I-5 and travel over the freeway. The project adds high occupancy vehicle lanes to Interstate 5, both southbound and northbound, between state Route 526 and U.S. 2 in Everett. It will help fix one of the state’s most notorious bottlenecks by improving safety, reducing merge challenges and moving traffic more smoothly through the area. When finished, additional lanes will make room for more cars. A new merge lane will be added in both directions on I-5 between 41st Street and U.S. 2. Photos courtesy Atkinson-CH2M Hill, A Joint Venture Crews drilled down as far as 60 feet for the bridge’s 8- to 10-foot-diameter concrete piers. A new right-hand exit to Broadway Avenue will be constructed; the existing left-hand exit for carpools, vanpools and buses will be modified; 19 bridges will be widened or replaced; freeway on- and off-ramps will be improved; noise walls added; and water that runs off the freeway will be treated. Construction of the right-hand Broadway flyover bridge should be completed by June 2006.
