Hanley Road Corridor Study - St. Louis County Department of Highways and Traffic



PDF file of the design from I-64 to Bruno Avenue



PDF file of the design from Hanley Industrial Court to Laclede Station Road



This project expands Hanley to six lanes from I-64 to Laclede Station Road, with a SPUI interchange at Manchester Road. It eliminates most driveway entrances and exits as well as a few traffic lights, and basically turns Hanley into an expressway.



This looks like a pretty big project, though no construction date has been set that I can see. A contract has been awarded for final design for the southern half. What's interesting is that the preliminary design for the northern half conflicts with what MoDOT wants to do with the I-64 / Hanley interchange. MoDOT wants a SPUI, but St. Louis County wants to build a tunnel from northbound Hanley to westbound Eager, and have the eastbound 64 to Hanley exit in the southeast corner of the intersection, curling back to Hanley.



Does anyone know what the status is on this? Is St. Louis County working with MoDOT to come to some sort of compromise on the I-64 interchange?

What concern is there for a pedestrian? Can people walk safely on sidewalks from place to place? Has right-of-ways or in-street rail been considered for future modern streetcars or Bus-Rapid Transit?

St. Louis County received an $8 million earmark in the last transportation bill for Hanley Rd. The earmark is from I-64 to south of Rt 100(Manchester). My understanding is that this money will go towards design and right of way purchases.



I personally think the County should spend its resources towards maintaining their many other roads, many of which are glorified country roads in poor condition and have no sidewalks. This project will be the poor man's I-170, seeing that the plan is to build 6 lanes and move traffic as quickly as possible.



To answer the first question, those drawings are older and were made before the I-64 reconstruction project became reality. St. Louis County will have to work with MoDOT to make sure their project fits in.

Haha...that was a joke right?

Anybody know whether St. Louis County is still planning on building a tunnel from NB Hanley to WB Eager. I would think the highway reconstruction would make a perfect opportunity to get said tunnel made, as crazy as it may be.

It looks like they do. The ink is in blue and it's a left lane and it starts decending in front of the Home Depot.



It also looks like they might want to get rid of the McDonalds. It has red borders around the property and says "Acquisition or Access Relocation"

Any sort of tunnel on Hanley will not be part of the I-64 project, those renderings have been posted on the website. As of now the County has money committed for design/right-of-way purchases along the Hanley Road corridor and nothing for construction. The final design for Hanley will begin shortly.

Two misconceptions here:

1) Hanley is a County project, not a MoDOT project

2) Post Hwy40 reconstruction, it will NOT be possible to go from NB Hanley to WB Eager. Eager at Hanely will become right in, right out. It will be necessary to turn left onto Dale and shimmey around Best Buy and Sports Authority to get to Dierbergs from NB Hanley.

Now I'm confused...are those two the MISconceptions, or the correct conceptions???

#1 is correct. Regarding #2, access from northbound Hanley to Eager will be removed, however, Brentwood is working on extending Strassner to Hanley so that there will be additional access to the stores on Eager from the south.

Then what am I seeing in the drawing that looks like a tunnel?



Where are you getting your information concerning #2 from?



-On page 8 of the PDF it says "Grade separation of NB I-170 traffic (left turn onto Eager Rd) with a one way tunnel"

-On page 12 they show a picture of the proposed tunnel.

whoops, that's what i get for writing posts in my head and not in the provided box... let me rewrite that...



Things that seem to have been misunderstood in prior posts and need to be clarified:

• Hanley widening is a county project, not a MoDOT project

• Post I-64, as planned right now, Eager Rd at Hanley will become right-in right-out, no left turns allowed. Left turning traffic will have to use Dale.



And what I want to know is whether St. Louis County still has plans to build that tunnel that would allow traffic from NB Hanley to Eager. Since Hanley is going to be ripped up anyways because of highway construction, it just seems to be the perfect time to dig underground, if that's what they're planning to do.



Is that clear now?

Yep. You kinda made it sound like the tunnel was dead. I was hoping you didn't have inside information that they were axing it.

Those drawings are pretty old and predate any of the I-64 reconstruction plans at Hanley. I imagine the County is still planning on creating some sort of access to Eager from NB Hanley, but that won't be known until they release their new plans.

Looks like the County is proposing 'Michigan Lefts' at the Hanley/Manchester intersection instead of building a full blown interchange. Personally, I feel an interchange would have been a waste, but it'll be interesting to see how people handle Michigan Lefts. I've never seen one before.









St. Louis County may go with 'Michigan Left' at Hanley-Manchester



By Phil Sutin

ST. LOUIS POST-DISPATCH

12/31/2008



St. Louis County may scrap its plans for an overpass taking Hanley Road across Manchester Road, and instead use a so-called "Michigan Left" intersection to move traffic better at the heavily traveled site.



The county's main concern is the cost of right of way for an overpass.



But the overpass idea also drew criticism from officials in Maplewood and Brentwood, where the intersection is situated; from County Councilwoman Barbara Fraser, who represents the area; and Trailnet, on behalf of bicycle riders. An overpass would have forced bicyclists and pedestrians to go down a ramp to Manchester, cross it, then go up another ramp to get back on Hanley.



Garry Earls, the county's chief operating officer, says that a Michigan Left, if properly designed, could handle the traffic as well as an overpass.





In a Michigan Left, a type of intersection common in that state but rare elsewhere in the country, left turns do not occur where the two roads cross, but in U-turn lanes in medians about 660 feet from the intersection.



About 60,000 vehicles a day travel through the Hanley-Manchester intersection — making it among the 15 most heavily traveled of the 700 intersections in the county's arterial system.
