Iowa transportation officials say they plan to print state road maps just once every two years.
The Waterloo-Cedar Falls Courier reports the state Department of Transportation will switch from annual printing to a two-year cycle in 2016.
The agency also plans to drop its usual print of 1.4 million maps to about 600,000 maps for the current budget year because of funding restraints.
The agency's chief says he asked Gov. Terry Branstad on Thursday to increase map production costs in 2014 and 2015 to allow for more map printing before the switch.
The DOT also says it will go on a two-year printing cycle in 2016 for the agency's separate transportation map for bicyclists.
