GREENWOOD, Ind. (AP): Officials say construction of a new Interstate 65 interchange in a southern Indianapolis suburb is being delayed for a year.

The state highway department says it hasn't been able to reach land purchase agreements with five property owners for the project at Greenwood's Worthsville Road. The agency is asking a judge to force the sales.

Greenwood development director Mark Richards tells the Daily Journal that the city is moving ahead with widening the road to four lanes in anticipation of the interchange.

State officials now plan to hire contractors in September and start construction of the interchange in the spring of 2015, with completion anticipated that year.

The project is estimated to cost about $22 million, with Greenwood paying up to $11 million of the cost.
