Mathews Bridge Expressway?

[Jaxson]

What traffic pattern change is planned for the expressway leading eastbound from downtown to the Mathews Bridge?  I noticed the flashing signs saying that the 'traffic shift' will begin on 1/25/11 and will end on 3/31/11.  What's going on here?  Just wondering because I travel between the urban core and Arlington quite often.

I would also be curious.....
are there plans anywhere for possible changes to the Union Street expressway?

I just searched jacksonville.com and got zero, zip, nada.

Here you go:

Arlington Expressway (State Road 10A) Rehabilitate the Palmetto Bridge overpass. Superior Construction Company of Jacksonville should begin January 21, 2011 and finish in 70 days at a cost of $329,742.97. Kenny Geisendorff/project manager.

BTW, PLEASE NOTE: It is properly called The Arlington Expressway from Liberty Street East to Regency.

A couple of years ago there were plans for a total reconstruction of all of the spaghetti loops and flyovers at the base of the Matthews and Hart online.

that PD&E study was never finished...and is now not consistent with the region's long range transportation plan....in essence, it wn't happen!

TUFSU what is the AADT on the bridge today?

TUFSU what is the AADT on the bridge today?

66,500 on the east end of the bridge.

thanks cline.....

and FYI, the generalized daily capacity at LOS D for a 4-lane expressway is 67,000....LOS E (max. theoretical capacity) is 75,000...so basically, the bridge is operating at near capacity today.

but the real question is this....does anyone think there will ever be a need for more than 6 lanes (capacity at LOS D is 104,000)?

[Ocklawaha]

Density might account for some increase in capacity, and there is still infill going in between Regency and the Intercoastal. I'd agree that it probably has a ceiling on it and 6-8 lanes is about as high as well see in any of our life times.

The problem is not solely traffic related though, the bridge itself needs some serious work. I would think the location of both the Matthews and Hart being on a curve in a flowing river are sitting ducks for scour, though it's probably not nearly as bad as downtown's bridges.

agreed Ock...when the bridge gets replaced, it should be built as 6 lanes....with additional space set aside for bus lanes or rail

What are the chances of any Matthews Bridge work opening up this portion of Hogans Creek?

Right now it is a culvert and cannot be navigated.  Someday opening the creek up from Springfield to the Shipyards would be HUGE.
