The legislation would be a plan for reducing freight bottlenecks and congestion across the country, and increase funding for grade separations, to build bridges and tunnels to separate roads from rail.
In a news release, Cantwell said the U.S. must improve its freight infrastructure to remain competitive. Freight delays cost the U.S. economy about $200 billion a year, according to Cantwell.
The bill would authorize spending $2 billion a year through 2021 on multimodal freight projects.
There is also a smaller amount of money for upgrading short-line tracks where they intersect with mainline tracks.
The bill doesn't have bipartisan sponsorship, but is supported by the Coalition for America’s Gateways and Trade Corridors, which is a lobbying arm for government transportation planning organizations, ports, engineering firms and government transportation agencies.
