U.S. state ofWashington . It is convert|4.52|mi|km|lk=on in length and runs from Mukilteo in the west to Everett in the east. It serves as a vital connection to Boeing's Largest Manufacturing facility atPaine Field , as well asWhidbey Island . It is often called the Casino Freeway because it is paralleled by Casino Rd. for much of the route, and prior to the construction of the freeway, Casino Rd. occupied much of the right-of-way.Route description
SR 526 starts at an intersection with State Route 525 in Mukilteo and climbs an extremely steep hill to an intersection with State Route 525 Spur. The route makes a turn on to the
freeway portion and squeezes between agulch and the primaryrunway atPaine Field . The freeway passes under ataxiway between two sections of Boeing and has an interchange with Airport Rd. The freeway continues along the front of the Boeing plant, the largest building in the worldFact|date=March 2008, to Seaway Blvd. the main access road to the Boeing facility. The freeway expands by a single lane and continues to an interchange with Evergreen Way, while a left-hand exit for I-5 north separates from the freeway under the overpass. On the other side, another lane is added as an exit to I-5 and an HOV lane to I-5 south. The freeway ends at atraffic signal at the northern terminus of both SR 99 and SR 527.History
Prior to the 1964 renumbering, SR 526 was SSH 1I from Mukilteo to Everett. The rest of SSH 1 became SR 525.
Prior to the completion of the current freeway alignment in the 1980s, SR 526 followed the course of 5th St. in Mukilteo and Mukilteo Blvd. and 41st Street in Everett. While the names may change, it is in fact a single highway. The former terminus of SR 526 in Everett was at the interchange between I-5 and SR 99 (now the 41st Street & Broadway interchange with I-5, also known as Exit 192)
When
Boeing expanded their factory in the early 1990s, the state ofWashington required that Boeing pay for upgrades to the connection between SR 526 and I-5.Fact|date=March 2008 These upgrades resulted in a direct connection being built to connect SR 526 to I-5 north, whereas previously one had to travel south on SR 527 in order to connect to I-5 north. Additional upgrades included anHOV queue lane for the I-5 southbound on-ramp, and the construction of sound walls along the freeway.Recent and future improvements include expansion of the interchange with Evergreen Way, realignment with
Washington State Route 525 Spur , and addition of HOV lanes.Exit list
The entire route is in Snohomish County.
