I thought there was discussion a few years ago about replacing the bridge on 55, but it never happened.  I-40 had some work done a few years back to make it more quake resistant.

Neither of those bridges comply with current Interstate highway standards. The I-40 Hernando de Soto Bridge may sport 3 lanes in each direction, but there are no inner or outer shoulders. The I-55 bridge is just 2 lanes in each direction. The road looks so narrow I worry about trading paint with other vehicles while crossing. The only positive thing I can say about the I-55 bridge is it does provide pedestrian and bicycle access on paths attached on the outer edges of the structure.

Have you ever driven that segment of 55 north of 240, Bobby?  Even at rush hour, it flows pretty well, and certainly doesn't need "four or five lanes in each direction."  The vast bulk of the problem is the Crump interchange.  Fix that, fix the lane drops so you have a consistent 6 lanes, and twin the river bridge if you have to.  That's all that's really needed on 55.

Yes, I've driven it before but usually avoid it and take I-40 instead. I've seen pretty good traffic back-ups on both sides of the I-55 bridge. If the traffic through that stretch of I-55 is flowing well at all during rush hour it's probably because others are just avoiding that zone of Memphis entirely.

(while the I-55 bridge does technically have walkways, they don't connect to anything on the Arkansas side, and the Tennessee side has been horribly unmaintained)

Due to the Crump interchange, as previously noted.  The rest of I-55 from Crump to 240 is generally fine.

Considering the two Memphis-area crossings (I-55 and I-40) are the only two Mississippi River crossings along a span of over 150 miles, it would be hard to say that building the other "half" of I-269, providing two additional river crossings, wouldn't be justified.

Granted, such would be a challenge both fiscally and coordination-wise with one state, much less three, but all three would reap their fair share of the benefits. I would think it would be in the long-term vision, maybe as part of a 50-year regional plan, if nothing else.

I would love to see 269 extended across the river into Arkansas. I think it would increase commerce in Those towns in east Arkansas en route to Little Rock. Not to mention, I could make it to Little Rock From Atlanta in a little over 7 hours. In what used to be 8 and a half-9 hour hour drive...

^ Still an improvement over the previous single-lane loop plus weaving-situations.

Just barely given the tight radius of the cloverleaf quadrant and the rather large amount of semi traffic that would have trouble keeping their lane .  The only way it isn't a bottleneck would be to replace the northbound cloverleaf with a flyover.  Not that it would likely be a priority anytime soon.  A southern I-269 that attached to I-55, or better yet, I-40 to bypass West Memphis as well, would be a boon to interstate travel.

Improvements are planned to make I-55 the through route with the removal of the cloverleaf: https://www.tn.gov/tdot/projects/region-4/interstate-55-crump-boulevard-interchange.html

I have walked across the I-55 bridge on the sidewalk.  I cringe to think about what it'd be like now, almost 33 years later.

I'd like to see a publication date of that TNDOT info release; AFAIK a positive ROD was issued several years ago; but the TNDOT article cites problems with the MPO's methodology re determination of need -- so it's back to the proverbial drawing board at least as far as approval is concerned.  The plans illustrated with a direct set of continuous lanes plus a roundabout replacing the old Crump interchange haven't changed since first proffered back about 2010; but since then one thing or another has prevented the project from advancing.  My guess is that even if "green-lit" in terms of the necessary approvals, this would still remain well down TNDOT's priority list.

I am guessing it's about the funding and priority list. With the two-lane ramp now in place, it has resolved one of the thorniest issues with the interchange. The rebuild would only increase traffic speeds and simplify that interchange further, but it doesn't seem to be an immediate need.

^^ The ROD was issued in 2012.  TDOT had an active plan to begin the project ca. 2015-16 but put it on hold after local opposition surfaced to their plan to shut down the bridge during some of the construction.  Then the project was defunded.

It's still possible to walk across those bridges, even if there are no sidewalks continuing the pathway on the Arkansas side. The pedestrian path on the adjacent railroad bridge is a new thing (built in 2015). I got a chuckle out of the current Google Earth imagery of the end of the sidewalk on the Arkanas side of the bridge (NB lanes). Someone left a recliner there at the end of the sidewalk. Someone could take a load off after the end of their stroll across the bridge. Watch out for creepy crawlies though.

Due to the Crump interchange, as previously noted.  The rest of I-55 from Crump to 240 is generally fine.

Three lanes in each direction is fine for now, with that crappy existing I-55 bridge and I-69 nowhere at all near completion. If the I-55 bridge was replaced and I-69 completed there would be quite a bit more traffic going through that zone. I would expect traffic counts to starting getting more of a bump just from I-269 and I-22 being completed.

The other alternative to improving I-55 in SW Memphis is widening I-240 and I-40 in downtown Memphis. That might be even harder to do. So, once again, with all those deficiencies noted, it makes a stronger case for a new bridge cross down by Tunica -extending I-269 across the river and up to I-40. It would divert a lot of long-distance, thru traffic. Then the folks within Memphis can do whatever. Tear out I-55 and turn it into a surface street. Let the old 4-lane bridge fall into the river.

Once the pedestrian trail opened on the Harahan Bridge, they closed the Memphis & Arkansas to pedestrians.

Quote
The Memphis & Arkansas Bridge carries U.S. Highways 61, 64, 70 and 79 from Memphis to West Memphis; it also carried U.S. Highway 63 prior to its truncation (and later rerouting) in Arkansas. The western terminus of Tennessee State Route 1 sits on the Tennessee-Arkansas boundary halfway across the bridge.

The bridge consists of five Warren through trusses, each with a length of 790 feet (240 m). Combined with the approach segments, the bridge's total length is 5,222 feet (1,592 m). Completed in 1949, it is the only bridge spanning the Mississippi River designed to carry exclusively vehicular traffic that was built before 1950. it was designed by Modjeski and Desoto, successors to the firm that designed the Harahan Bridge, built in 1916 to carry vehicular and rail traffic.[3] The bridge was listed on the National Register of Historic Places in 2001.[1]

Having been built before the introduction of the Interstate Highway System, the span was not built to Interstate Highway standards, lacking the concrete barrier between the different directions of traffic which was added later. It was also built with a sidewalk on either side of the roadway, positioned just outside the steel truss girders. The sidewalks, now also separated from the traffic lanes by concrete barriers, are accessible from Memphis city sidewalks on the Tennessee side, but give way to grassy slopes on the shoulders of I-55 on the Arkansas side.

The sidewalk and bridge is listed as part of the Mississippi River Trail. However, travel is not recommended across the sidewalk and is prohibited on the vehicle traffic lanes of the bridge, being an Interstate highway crossing. On August 12, 2012, a cyclist was killed after being struck by a vehicle when using the shoulder approaching the bridge.[4] In 2016, a pedestrian/bicycle path on the neighboring Harahan Bridge made crossing the river safer and eliminated the need to use the I-55 bridge.[5]

On Tuesday, December 23, 2014, numerous news sources reported that the FBI had released an official statement warning local law enforcements of a threat to the bridge during that month. The FBI stated, "According to an anonymous complainant... ISIS instructed an ISIS member, a presumed USPER (U.S. person) in Memphis, with a direct order to blow up the Memphis-Arkansas bridge on an unknown date, activating ISIS terror cells in the United States." Security was heightened, but the threat was later discredited.[6]

Citation needed for the I-55 sidewalks being closed to peds (rather than just bypassed).
