After 50 years of heavy use, the Washington State Department of Transportation (WSDOT) said a nearly 22-mi. stretch of Interstate 5 between Seattle and Kent “is about to get a much-needed facelift.”The agency said it is starting “one of its most ambitious interstate restoration projects,” to rebuild that part of northbound I-5 over the next three years.
AASHTO announced that it has chosen three employees of state departments of transportation to work in the coming year at association headquarters in Washington, D.C., as winners of 2017 Transportation Management Fellowships. Two of them will be engineering fellows and one will be a policy fellow, and will start arriving at AASHTO in early April.
Sixty-four years to the day the Alaskan Way Viaduct in Seattle opened to traffic, the tunneling machine dubbed “Bertha” emerged into daylight from a 1.7 mi. (2.7 km) drive beneath the city. The crew broke into the 90-ft. (27 m) deep disassembly pit at 11:25 a.m.
When Friday rolls around, crews on the Point Defiance Bypass Project are ready to attack their job building new rail line, but when Monday arrives, it's back to business for the railroad. It's a tightly synchronized operation of a $150 million project that will make rail travel all that more efficient in the corridor stretching from Vancouver, B.C.
Since its opening in 1963, the state Route 520 Bridge provided Seattle and Eastside residents a shortcut across Lake Washington. By the 1990s, its 1950's design couldn't accommodate the increased number of vehicles crossing the lake, resulting in lengthy backups during rush hour.
Nobody is happier about the improvements under way at the King Street Station than the conductors aboard the trains that stop at the historic Seattle terminal.
The improvements will automate 21 switches that conductors currently must throw by hand. Scattered along 2,000 ft.
Three years after the tunneling machine dubbed “Bertha” began work on a 2-mi. (3.2 km) tunnel beneath the city of Seattle, the machine has passed the half-way point. Bertha pushed past the Pike Place Market on Sept. 30, successfully excavating more than 4,635 ft.
Bridges owned by the Washington State Department of Transportation met an annual performance goal of having at least 90 percent of deck area in fair or better condition, despite a slight decrease from one year ago. In its 62nd edition of the “Gray Notebook” quarterly performance report, WSDOT examines the reasons 92.1 percent of WSDOT-owned bridges by deck area were in fair or better condition in 2015 and notes why they declined to 91.2 percent in 2016.
Things are going to look a little different in the next couple of days across Snoqualmie Pass as we get ready to put all four lanes of traffic on the new avalanche bridge. This is all part of the major improvement project to widen a 15-mi. (24 km) stretch of I-90 from Hyak to Easton.
Since the I-5 Madigan Access Improvement project's start in October 2015, drivers traveling the stretch of I-5 alongside Joint Base Lewis-McChord (JBLM) had to contend with nighttime lane closures while users of Berkeley Street had to navigate construction on the southbound off-ramp and across the Freedom Bridge.
