Windsor. Leamington District Memorial Hospital in Leamington, Ontario, serves much of Essex County and, along with the Windsor institutions, share resources with the Chatham-Kent Health Alliance. Over eighteen thousand Windsor residents are employed in the health care profession. Transportation Windsor is the western terminus of both Highway 401, Canada's busiest highway, and Via Rail's Quebec City–Windsor Corridor. Windsor's Via station is the nation's sixth-busiest in terms of passenger volumes. Windsor has a municipal highway, E.C. Row Expressway, running east–west through the city. Consisting of of highway and nine interchanges, the expressway is the fastest way for commuters to travel across the city. E.C. Row Expressway is mentioned in the Guinness Book of Records as the shortest freeway that took the longest time to build as it took more than 15 years to complete. The expressway stretches from Windsor's far west end at Ojibway Parkway east to Banwell Road on the city's border with Tecumseh. The majority of development in the city of Windsor and neighbouring town of Tecumseh stretches along the water instead of in-land. As a result, there is a lack of major east–west arteries compared to north–south arteries. Only Riverside Drive, Wyandotte Street, Tecumseh Road, County Road 42/Cabana Road and the E.C. Row Expressway serve the almost from the west end of Windsor eastward. All of these roads, especially the E.C. Row Expressway are burdened with east–west commuter traffic from the development in the city's east end and suburbs further east. There are eight north–south roads interchanging with the expressway: Huron Church Road, Dominion Boulevard, Dougall Avenue, Howard Avenue, Walker Road, Central Avenue, Jefferson Boulevard, and Lauzon Parkway. Traffic backups on some of these north–south roads at the E.C. Row Expressway are common, mainly at Dominion, Dougall, Howard, and Walker as the land south of the expressway and east of Walker is occupied by Windsor airport and there has been little development. Windsor's many rail crossings intersect with these north–south thoroughfares. In October 2008, the Province of Ontario completed a grade separation at Walker Road and the CP Rail line. Another grade separation was completed in November 2010 at Howard Avenue and the CP Rail line. In both cases, the road travels under the rail line and both have below grade intersections with an east–west street. These were planned as parts of the "Let's Get Windsor-Essex Moving" project funded by the Province of Ontario to improve local transportation
