Dangerous curve near Topeka scheduled for study

TOPEKA, Kan. — Local and state highway authorities are looking for ways to remedy a treacherous Interstate 70 curve near downtown Topeka, Kan.

Funding has been approved for a new study of the problem.

The curve is part of the Polk-Quincy viaduct, built in 1963. It carries interstate traffic above city streets for nearly a mile around the north side of the downtown area.

Stan Whitley, a spokesman for the Kansas Department of Transportation, said KDOT doesn't record accidents specifically at the one sharp curve but for the whole viaduct.

During the 10-year period from 1997 to 2006, there were 102 accidents on the viaduct, ranging from a low of three in 2003 to a high of 16 in 1998. No one was killed in those accidents, but 42 people were injured.

In December 2008, it was announced that $735,000 in federal funds had been approved for a study of how to improve that kink in the highway. Cost estimates range from $100 million to $200 million.

Steve Swartz, KDOT public information officer, said the money for the new study will look at options that include widening the highway to three lanes in each direction and straightening the viaduct while keeping in mind how any change would dovetail with the city's plan for riverfront development. He said the options to be studied likely would include creating a new route and building it at ground level.

KDOT already has made some cosmetic changes in the area to call attention to the lower speed limit. Special reflective sheeting and reflective tabs have been placed on the concrete barriers, and flashing lights have been added to signs warning of the 45 mph speed warning through the curve.
