said by bigballer:How the heck is it costing $2.1 billion to expand 294 to 10 lanes for 22 miles when it cost $2.2 billion to expand 90 to 8 lanes to Randall and to 6 lanes to 39? That was 22 + 37 miles of roadway.
Isn't the part being expanded the "Central" part -- basically between 55 and 90? A lot of the Tri State near the southern edge of O'Hare is elevated -- expensive. I would imagine reconfiguring the 88/290/294 interchange for a wider 294 is also is pretty pricey. And if it also includes widening the "Mile Long Bridge" just south of I-55 before the Toll Booths, that also is probably pretty pricey
And while they are at it, probably building the approaches and ramps for the future O'Hare Ring Road Bypass Tollway to connect over to the Elgin/O'Hare
Plus it is probably one of the busier roadways and roadway segments in the State - gonna be a lot of off hours scheduling and working in "phases" to maintain as much traffic capacity as possible.
I don't find it that unreasonable that the Central Tri State would cost a lot more than I-90 out to Rockford.
BTW are there any improvement plans for the I-90/I-290 interchange? Way too much traffic for a functional cloverleaf...
