A plan from Kansas House Republicans would divert $320 million from highway projects to replace revenue lost by a cut in state income taxes.

A spokesman for the Department of Kansas Transportation says some highway projects could possibly be delayed or shelved if the proposal is approved.

St. Marys Republican Rep. Richard Carlson, chairman of the House Tax Committee, says financing for the transportation department would stay the same in fiscal years 2014 and 2015, before climbing again in 2016.

The Topeka Capital-Journal reports the GOP plan is an alternative to one proposed by Gov. Sam Brownback, who wants to extend a 0.6% increase in statewide sales tax. The House plan would let the sales tax fall back to 5.7% and replace the revenue with KDOT money.
