Republican leaders in the U.S. House of Representatives may scale back a $260 billion transportation bill in order to quell controversy and improve chances of the measure winning approval in coming weeks.

Sources with knowledge of discussions on Capitol Hill said on Thursday that House leaders may drop their five-year package in favor of shorter and less expensive plans for road, bridge and transit construction.

The Democratic-controlled Senate is simultaneously considering a $109 billion measure over two years but House leaders have not committed to a new timeframe or an amount, the sources said.
