Big mistakes were made by the State Department of Transportation in its construction of the pontoons that will hold up the new 520 bridge across Lake Washington.

The agency says it is making repairs and design modifications to ensure the bridge will last the full 75 year lifespan promised.

State lawmakers may reconsider the law that requires new ferries to be built in Washington.

An audit suggested ferries could be built cheaper at shipyards out of state.

The Daily Herald reports the audit is the subject of a legislative hearing Wednesday in Olympia. The audit cost $1.2 million and took a year to complete.

PORTLAND - Washington and Oregon are getting serious about finding a replacement for the gas tax. Steadily improving fuel efficiency in cars is eroding the primary source of road funding in the Northwest. A new report to the 2013 Washington Legislature finds it "feasible" to have drivers pay by the mile instead. In Oregon, lawmakers have actually drafted legislation to do just that.

Suburban Portland SUV owner Mary Olson has possibly glimpsed the future of how we'll pay for roads, although it's tricky to spot.

If you have to drive this weekend, you should plan on leaving a lot of extra time, as several major roads will be completely closed.

"Everybody is going to be touched by this weekend’s construction, whether you live in Renton or Seattle or Bellevue or Lake Stevens or Snohomish," says Jamie Holter with the State Department of Transportation.

Seattle Mayor Mike McGinn has been calling for a closure of the Alaskan Way Viaduct as soon as possible.  That's because it's an earthquake hazard.  Other leaders think that's an over-reaction, since a new tunnel is already in the works. 

But the Viaduct will close this weekend for its semi-annual inspection.  Drivers will have to re-route their travel for two days.  Routine maintenance on the old structure was scheduled long before the earthquake in Japan.

While it's a good idea to be prepared, sometimes it's good not to move too fast. 

Apparently there are glitches in the state's new "Good to Go" tolling system.  The State Department of Transportation says it will revamp the sign-up process after complaints by frustrated motorists trying to buy transponders online.  As Mike Lindblom reports in The Seattle Times:

State transportation officials have announced the likely winner in the competition to build a tunnel to replace Seattle's aging Alaskan Way Viaduct.  The proposal comes from a consortium known as Seattle Tunnel Partners.  It has a slightly higher price, but offers other benefits.
