A tie in the U.S. Supreme Court may cost Washington state $2 billion.
The court’s 4-4 split Monday settled a long-running court battle between tribes and the state over salmon-blocking road culverts.
Culverts are the pipes and tunnels that carry streams under roads. If they’re designed poorly they can block salmon from swimming to habitat upstream where they reproduce. Washington state owns more than 800 culverts that block more than 1,000 miles of streams.
