If you believe that trucks move America, then the state of Washington is contributing to slowing that progress down, based on a recent analysis of the most congested bottlenecks for trucks in the United States. It shows that six freeway intersections in the state, including two in the city of Seattle, rank among the 100 worst bottlenecks for trucks in the nation.
The American Transportation Research Institute (ATRI) conducted the study using GPS data from more than 1 million trucks as well as custom software applications and "an algorithm that quantifies the impact of congestion on truck-based freight." The measures of freight movement are important to understanding where key infrastructure investments need to be made to help improve the nations transportation system, according to ATRI.
“Washington's vibrant economy moves in our state's trucks,” says Washington Trucking Association Executive Vice President Sheri Call. “As our economy grows, as our trade relationships with Canada and across the Pacific improve, congestion will be a threat to put the brakes on our economic prosperity unless we address our crumbling infrastructure. Congestion ultimately impacts the cost of goods being hauled on trucks held up by needless delays ― the cost of doing nothing is one we all pay.”
The six freeway intersections in Washington making the list of the nation’s top 100 worst bottlenecks, according to ATRI, are as follows:
- No. 34 Vancouver: I-5 at Columbia River― average speed 41.6 mph; peak traffic average speed, 35.4 mph.
No. 35 Tacoma: I-5 at I-705/SR 16 ― average speed 39.1 mph; peak traffic average speed, 31.7 mph.
No. 39 Federal Way: SR 18 at I-5 ― average speed 42.1 mph; peak traffic average speed, 32.9 mph.
No. 44 Seattle: I-5 at I-90 ― average speed 32.7 mph; peak traffic average speed, 25.6 mph.
No. 60 Auburn: SR 18 at SR 167― average speed 43.7 mph; peak traffic average speed, 35.7 mph.
No. 76 Seattle: I-90 at I-405 ― average speed 36.6 mph; peak traffic average speed, 28.6 mph.
The top 10 most congested freeway bottlenecks in the nation are located in Fort Lee, New Jersey; three freeway intersections in Atlanta; Nashville, Tennessee; Houston; Chicago, Cincinnati and two freeway intersections in Los Angeles.
