Locations where Auxiliary Lanes are needed

[webny99]

Ontario really loves two-lane exits (with the rightmost thru lane as an option lane). I hadn't thought of the potential this has for queue reduction, but that's an excellent point.

[TheOneKEA]

MD 32 westbound is missing an auxiliary lane between the on-ramp from Dorsey Run Road to the C-D lane for the US 1 interchange. MD 32 eastbound does have an auxiliary lane between these two interchanges.

[Mergingtraffic]

CT tends to have too many where it creates more traffic slow downs.  They are too short to really be useful but during rush hour people use them as passing lanes and then merge back in and slows down traffic.  I-84 in western CT has this a lot.

Other times CT will end the "slow vehicle lane" half way up the hill. typical.

I use the longer climbing lanes to pass slow traffic. Passing on the right with three or more lanes is legal here.

In Illinois:

* I-290 between Woodfield Road and the I-90 ramps.
* I-290 EB between the EB St. Charles Road entrance and the ramp to SB I-294 (can't remember if one is being put here as part of the Tri-State rebuild)
* Several spots on I-55 east of I-294

I think I saw St. Charles Road area may be part of plan. Need to find that doc.
I-290 / I-90 needs alot more.

Bump, but I think auxiliary lanes are needed here:

US-264 at Bell Rd

I-40 at Conover - Long merge lane but I do think an auxiliary lane is needed due to the fact my friends were actually driving in the merge lane that was ending! Example

[ibthebigd]

Lexington Ky

Winchester Rd interchange and the I-64 split on I-75

SM-G950U

[skluth]

They added them in most of the needed places during my decades in St Louis. However, these places still could use aux lanes

I-55 between Gasconade and President/Potomac
NB I-55 between Union Road and Bayless
NB I-55 from the cloverleaf ramp at IL 157 to the top of the bluff
I-55 between US 40 and IL 162
I-70 between West Florissant and North Broadway
WB I-44 between Grand and Jefferson
I-44 between Southwest and Hampton

For Cincinnati:

- I-75 between OH 562 and OH 126. I was on OH 562 getting onto I-75 NB a week ago, and the exit ramp backed on on 562 all the way to the OH 4 exit, because of the short merge area on I-75. Also the Towne St ramp removal on NB I-75 would help too.
- I-71 between US 22/3 and Pfeiffer. Especially the SB direction between 126 and 22, where mall traffic back up on the freeway. An auxiliary lane already exists for SB 71 between Pfeiffer and 126, but would be nice to extend that to the US 22 exit, as previously mentioned, and add them to the NB lanes.

[SkyPesos]

Found this while browsing GSV, this would be a great candidate for auxiliary lanes, considering US 60 east of Phoenix have so many tightly spaced exit ramps like this:

[I-55]

I-69 between Exits 316 and 317 in Indiana. Allen County has rapidly sprawled on the north side and the southwest side. Union chapel Road (Exit 317) is the last exit north in Allen County before the Dekalb County line (Mile 322) and the next exit is at Co Rd 11A (Exit 326). The stretch between 316 and 317 is where the 3rd lane each way ends, so traffic on I-69 is less spread. Add in everyone entering from Union Chapel with little merge room and you have congestion.

[chrismarion100]

Here are some for Wisconsin Us 53 from Us 12 to River Prairie Drive and from River Prairie Drive to Wi 312 and one on Wi 29 from county highway X in Lake Wissota to Wi 29 BUS / 178

[ran4sh]

Georgia 10 Loop from exit 6 to exit 15. Which is about half of the length of that route, but it has 2/3 of the exits. Along that stretch there is about 1 exit for each mile, but only 2 auxiliary lanes currently exist (along the Outer loop from exit 11 to exit 12, and along the Inner loop from exit 11 to exit 10C).

[chrismarion100]

On US 53 in Eau Claire, one will be needed between WI 312 (North Crossing) and River Prairie Dr and another one between River Prairie Dr and US 12 (Clairemont Ave)

[webny99]

I've long wanted to see one on I-90 (each direction) between exits 36 (I-81) and 37 (Electronics Parkway).

Yeah, came back here to second that and also note that I-87 could use auxiliary lanes between NY 144 and the Berkshire Connector.

I'd really like to see the entire segment from I-787 south to the Berkshire Connector widened to six lanes... hopefully the construction just south of I-787 is a step in the right direction, at least for a slight extension of the six lanes if not a longer widening project.

[JCinSummerfield]

Definitely US-23 between I-94 & US-12 in Washtenaw County, Michigan.

[thefarmerchris]

I-69 between Exits 316 and 317 in Indiana. Allen County has rapidly sprawled on the north side and the southwest side. Union chapel Road (Exit 317) is the last exit north in Allen County before the Dekalb County line (Mile 322) and the next exit is at Co Rd 11A (Exit 326).

If INDOT is smart, they will also add in an aux lane on NB I-69 between Coldwater Rd and I-469 solely because of the traffic jam that occurs during the day. Maybe when they modify the 469/69 interchange in a couple years it'll get rectified.

[MikieTimT]

This is one that is almost indefensible since it was just completed a little over a year ago.  I-49 between the Wedington Dr. exit (current exit 64, until they renumber the exits to account for mileage down to Louisiana like the soon to be or already open newer sections of I-49) and Porter Rd./Mt. Comfort Rd (Exit 65).  Those exits are already less than 3/4 mile apart from each other to begin with, so that leaves less than half a mile of enforced merging, so anyone who is travelling through is pretty much forced into the center or left lane to keep from hitting brakes heavily (or stopping altogether as off-ramp traffic backs up onto the shoulder) during peak times.  They had the right-of-way already when they did the 6/8 lane expansion in Fayetteville, but couldn't be bothered to pave another 1/2 mile in each direction to keep the on-ramp as an off-ramp.  At 4:30PM onward, southbound I-49 traffic backs up onto the shoulder awfully close to the end of the on-ramp from Porter Rd. anyway, and it's hard to get over enough to stop on the shoulder with such a short one lane off-ramp onto Wedington Dr.

I-49 Exit 64 southbound
I-49 Exit 65 northbound

MN 62 between France Ave and Xerxes Ave.

[tolbs17]

Desperately needed here. I might have to request or find plans to add an exit lane here (and widen the exit ramp to two lanes) as well as reconfiguring the nearby NC-97 interchange.

In this plan, I-540 will get auxiliary lanes at every single interchange. I believe it's from US-70 to Capital Blvd (US-1). Ramp meters are a part of that plan too.

In the Buffalo area, I-290 has some egregious ones.

The most notable is between Exit 4 (I-990) and Exit 5 (NY 263). Heading east, the two lanes entering from I-990 collapse into the mainline in the span of about 800 feet, squeezing all traffic into the three thru lanes to pass under Maple Ave, only for a decel lane for NY 263 to open up almost immediately. And westbound, the two lane exit to I-990 is wasted by the bottleneck. It's even more egregious when compared to heading the other direction from I-990, which has a full 10-lanes between there and US 62. This setup should be mirrored heading towards NY 263.

I-290 WB also has a short 600-foot span between Exit 5 (NY 263) and Exit 6 (NY 240/324) with no auxiliary lane, though EB does have an auxiliary lane in this instance.

And then there's the eastern terminus of I-290, where new auxiliary lanes on I-90 have helped somewhat (especially on I-90 EB), but I-290 EB still backs up due to the auxiliary lane formed on I-90 exiting to NY 33 WB. A 500 ft extension to join the lane that opens up for NY 33 EB (shown here) would do wonders, and it's baffling why this was not done with the recent project. This would make a full 8-lanes in both directions between I-290 and the south side of the NY 33 interchange.
