DES MOINES (AP) — The Iowa Department of Transportation says it plans to spend a record $700 million on construction on state and interstate highway projects this year.

The Des Moines Register reports the department spent $656 million on road projects in 2014. A 10-cent-per-gallon tax gasoline tax increase, which took effect March 1, will provide about $200 million annually to cities and counties across the state. There are statewide plans to fill potholes, repair aging bridges and install new concrete and asphalt pavement.

Des Moines Public Works Director Jonathan Gano estimates the city's budget will receive an additional $3.7 million annually because of the tax increase.

Officials say that up to 500 work zones will be set up statewide from now until the end of the road construction season in November.
