There is an interchange project along I-64 just west of Union Station, currently entering Final Design, that will spell doom for the freeway stub at Exit 39. Current plans show a compact diamond at 22nd with an extension through Jefferson Ave., also removing the Market/Ewing ramps. While this design could change, the effect of killing off the old remnant of MO 755 is unlikely to. It had a good 50-year run.

The only question is:  will Revive 755 survive?  (hey, at least it all rhymes!)

Nah, I'll change my username to 'The Lost Cause'  :spin:

I don't see the need for a full interchange at 22nd.  Jefferson is much more deserving for a full interchange IMHO - it has better continuity, and could be used as an alternative route to WB I-44 in case a truck overturns on the ramp to WB I-44/SB I-55 from the PSB.

WB I-255 over the Mississippi River is closed through at least the end of the week due to a cracked beam.

IL-3 North to the Poplar St Bridge/I-55/64 is the recommended alternate River crossing, but MoDOT advises considering any alternate bridge

There are also the Chester and Cape Girardeau Bridges, for Downriver Southern IL traffic that might typically use IL 3 to utilize the Jefferson Barracks Bridge WB to reach MO

Not good news for the Westbound bridge...The tests are awaiting full results, but apparently MoDOT is already considering ultimately routing WB traffic on the EB bridge

Interesting how on the Missouri side there appears to already be enough pavement to have a crossover (Streetview, but there is nothing similar on the Illinois side.

If the westbound bridge faults require on longish-term closure to correct, will MoDOT and IDOT attempt to go 2 lanes, each direction, on the eastbound bridge?

There would be no shoulders, but there appears to be close to enough concrete surface to squeeze it in, maybe...Might have to make it slightly narrow lanes as well

Jefferson Barracks Bridges.

From Bridgehunter.com

Westbound bridge built 1984; eastbound bridge built 1990

Inspection report (as of May 2015)
Overall condition: Fair
Superstructure condition rating: Good (7 out of 9)
Substructure condition rating: Fair (5 out of 9)
Deck condition rating: Satisfactory (6 out of 9)
Sufficiency rating: 79.5 (out of 100)
Scour condition:   Bridge is scour critical; bridge foundations determined to be unstable.

http://bridgereports.com/1276128

I am not a bridge engineer, but if the foundations are in bad shape, the first thing you see is stress cracks up above.

Kind of like a sinking foundation of a house, the house stays together, but cracks start forming above the doors first.

Short version: 2 Westbound lanes will be open on the WB bridge during weekday morning rush hours (5 am-10 am), and 1 Westbound lane other times. Oversize and Overweight loads will be prohibited, until repairs can be completed

Lets hope there isn't anything higher than a 4.0 from the New Madrid for now.
