The torturously slow pace and increasingly expensive price to replace the Interstate 5 bridge across the Columbia River have some Oregon and Washington lawmakers growing uneasy and frustrated. Supporters of the project predict fewer crashes, faster commutes and more transit options when the new bridge is done. A final environmental review for the project was supposed to conclude this year, Oregon state Sen. Khanh Phạm, D-Portland, told the committee. Washington state Sen. Marko Liias, D-Edmonds, in an interview afterwards, preached patience. Oregon and Washington could go it alone, he said, but it would mean ditching light rail and other bells and whistles.
