Kansas Department of Transportation (KDOT) in the US has unveiled a plan to invest $651m in state-wide road and bridge projects that are scheduled to start during the next two years.

The projects will improve 1,404 miles of highway and replace 93 bridges in 2012 and 2013.

KDOT will also start preliminary engineering on 22 projects that will be considered for future preservation work.

The project will also include the reconstruction of a 1.3-mile stretch of US-24 highway, including an interchange and replacement of a bridge over Union Pacific railroad tracks in Shawnee County.

In addition, KDOT has launched a performance measures website to monitor the progress of the transport system, which includes condition, safety, project delivery, workforce, operations and non-highway modes.
