DES MOINES, Iowa (AP) -- The Iowa transportation department has denied Windsor Heights' request for traffic cameras in the city's section of Interstate 235 in the Des Moines area.

The city wanted to install two sets of speed cameras above the westbound lanes in the 1-mile section. Cameras have already been installed in Des Moines' eastbound lanes into downtown.

Windsor Heights Police Chief Dennis McDaniel says the transportation department sent a letter to the city last week, saying it wasn't comfortable with approving the request and that other options should be considered.

The DOT says other options could include real-time overhead speed displays and an increased presence by the Iowa State Patrol.

Daniels says the city will continue to work with the DOT, but plans to appeal to the decision.
