Some members of New York's Congressional delegation are calling for Washington to raise the federal gas tax to help fund local infrastructure projects, including the completion of the Second Avenue subway.

Congress members Carolyn Maloney and Adriano Espaillat are spearheading the effort, arguing that if the tax was raised one cent, it would create $420 million in state transit investments.

The push comes a few weeks before the one-year anniversary of the 2nd Avenue Subway opening.

The Congress members said the money could go towards completing the second phase of the subway line, extending the Q train through 125th St. in East Harlem.

It is expected to cost $6 billion, with about $2 billion coming from the federal government.
