WASHINGTON (AP) President Barack Obama is hitting the road again on a weeklong push on spending for roads, bridges and other public works.

Using the now-closed I-495 bridge at the Port of Wilmington in Delaware as a backdrop, Obama is to announce a new initiative Thursday to boost private-sector investment in the country's aging infrastructure. The bridge is a critical artery through downtown Wilmington, but officials closed it in June after four huge support columns were found to be tilting.

The House passed a measure this week to keep transportation aid flowing to states through May.

Obama says that's fine, but he spent the week pressing Congress for a more stable source of funding.

From Delaware, Obama was traveling to New York City to raise campaign money for the Democratic Party.
