Just what, exactly, $280 million will buy for transportation projects during the coming year will be disclosed this morning in Topeka.

Lt. Gov. Mark Parkinson and Deb Miller, Kansas transportation secretary, are scheduled to reveal a list of state transportation projects chosen to receive financing through the federal stimulus program, formally called the American Recovery and Reinvestment Act.

President Barack Obama signed the bill into law Tuesday.

Kansas will get $377 million for transportation projects through the program, of which $280 million will be used to whittle a list of $1.3 billion worth of projects previously identified by the Kansas Department of Transportation.

On that list, two projects involving Douglas County are under consideration:

l $10 million to build an interchange at the South Lawrence Trafficway and Bob Billings Parkway.

l $100 million to add two lanes to a six-mile stretch of the existing Kansas Highway 10, either in Douglas or Johnson counties.

The federal government also is pumping another $27 million into transit operations in the state, of which Lawrence is slated to receive $1.9 million. Those projects — with possible investments including the purchase of new buses, addition of new shelters and installation of new bus “cut-outs” along city streets — are not scheduled to be part of today’s announcement.

Another $70 million is coming into KDOT from the federal government, to be used to fund projects proposed by cities and counties. Of that total, $22 million will go to projects in the Kansas City metro area and $16 million will go for work in the Wichita metro area.

That will leave $32 million to be shared by all other communities. Lawrence, for example, has proposed a long list of projects, headed by $6.6 million to rebuild Kasold Drive, from Clinton Parkway to 31st Street; Douglas County also has forwarded several proposals, topped by $2.6 million to rebuild the Farmers Turnpike, from County Road 1029 to the trafficway.
