The $3.4 billion Columbia River Crossing -- a bridge, highway and light-rail project between Oregon and Washington state -- needs to clear several hurdles if it is to advance, according to this article. In particular, it has to get around the Washington state Senate's conservative legislators, who do not agree on raising gas taxes to get the bridge built. The state also needs to make a $450 million commitment before Oregon's pledge of the same expires on Sept. 30. The project "continues to have this zombie existence where it just stumbles forward and they continue to spend money on planning," said economist Joe Cortright. "It probably won't get approval for construction, but they won't kill the project outright either."
