Federal investigators released a preliminary report Tuesday about last month’s I-5 bridge collapse over the Skagit River. The report says the driver of the truck that struck the bridge before it fell had moved over closer to the edge of the bridge because of a passing truck.

The effort to replace the I-5 bridge that collapsed into the Skagit River last month has hit a milestone. On Monday, workers installed the framework for part of a temporary replacement that will eventually support the bridge’s north-bound lanes. There will be a second span to handle south-bound traffic.

Correction 6/4/2013: A previous version of this story had a typographical error. The bridge is scheduled to be closed June 5, not June 6.

King County plans to close an old bridge near Kent earlier than originally scheduled, officials said Monday.

The Alvord T. Bridge is both structurally deficient and functionally obsolete. It’s the first such closure since last month’s I-5 bridge collapse in Skagit County.

New streetcars might be running through downtown Seattle in a few years, under a plan announced Monday by Mayor Mike McGinn. The new route would be a link between the existing streetcar route in  South Lake Union, and the one under construction that will serve Capitol Hill, First Hill and Pioneer Square.

A parade of people who live and work near the collapsed bridge in Mt. Vernon continued to visit the scene today to get a first-hand look at the damage, snap photos and swap news about the accident.

“I’m scared to drive over other bridges,” said Jerry Olmstead, who works in Mt. Vernon and crosses this bridge several times a week. “What if another bridge in Washington goes?”

Cab drivers spoke out against new app-based car services during a Seattle City Council meeting Thursday. Companies such as Uber, SideCar and Lyft offer smartphone apps that allow users to book a ride by the touch of a button. Those business operations are mostly unregulated, and their presence in Seattle has led to questions about whether the companies are legal.

Driving around Seattle this weekend will be trickier than normal. The Seattle Department Of Transportation plans to close parts of Aurora and Mercer Street around South Lake Union as part of the effort to convert Mercer into a two-way street. The city's now focusing on the Mercer West project, the section of Mercer between Dexter Avenue and West Fifth Avenue.

National Bike to Work Day is May 17. That means lots more cyclists on the roads. Washington drivers should be even more careful, not only for safety reasons, but also because of a recent change to Washington state law.
