It was the mother of Washington County road projects, lasting three years and transforming a city that had developed a reputation for collisions on cross streets and agonizing waits behind the wheel.
Now the $41 million county mega-project is finished, with new highway overpasses and pedestrian bridges and reconstruction of Forest Lake's once-dangerous Broadway Avenue, the city's main business thoroughfare.
"The downtown area had crumbling infrastructure and massive backups at intersections," said County Engineer Wayne Sandberg, a Forest Lake native.
"If you were a family in a minivan and wanted to go to a restaurant, you had a bigger chance there than anywhere else in Washington County of being T-boned on Broadway."
Traffic in Forest Lake, a city of more than 18,000, had outgrown streets designed years ago when the area's population was far smaller. The city sits at a commuter gateway to St. Paul and Minneapolis and also funnels recreational traffic to nearby lakes.
Broadway Avenue was one of the most notorious stretches of road in Washington County because of its heavy traffic, merging difficulties and high crash rate. The road connects Forest Lake's downtown with Interstate 35 and Columbus in Anoka County.
Improvements along Broadway, also known as County Road 2, are substantial. The street was widened and turn lanes were added, and the county built a "backage" road behind businesses along the north side of Broadway to reduce traffic entering and exiting the busy road.
The Broadway Avenue overpass above I-35 was reconstructed with eight lanes instead of three.
