TARRYTOWN, N.Y. — The government is running out of money to repair deteriorating roads, bridges and ports, and President Obama says more federal spending will help avert a looming crisis that could stifle economic growth and torment commuters.

Obama’s visit Wednesday afternoon to New York’s Tappan Zee Bridge was a central part of his administration’s effort this week to call attention to the nation’s crumbling infrastructure.

The major Hudson River crossing point, which was opened to traffic in 1955, is now being replaced at a cost of $3.9 billion.

The financing is largely by bonds paid for through higher tolls.

In addition to promoting a four-year, $302 billion transportation plan that he wants Congress to back, the president intended to cite efforts to cut red tape and delays in permitting, according to the White House.
