Highway with most left entrances/exits per mile

[bugo]

I-244 is a left exit enthusiast's dream. It has left exits all over the place, even where they don't make sense. Here's a list I have compiled:

eastbound I-244:

Begins as a left exit
1st Street left entrance
US 64-412-OK 51 left exit
LL Tisdale Parkway left exit
Detroit Ave left exit
US 75 (I-444) left exit
US 75 (I-444) left entrance
Sheridan Rd left exit
Sheridan Rd left entrance
Memorial Dr left exit
Memorial Dr left entrance
OK 11 left exit
US 169 left exit

westbound I-244:
Memorial Dr left exit
Memorial Dr left entrance
Sheridan Rd left exit
Sheridan Rd left entrance
US 75 (I-444)left exit
US 64-412-OK 51 left exit
US 64-75-OK 51 (I-444) left exit
US 64-75-OK 51 (I-444) left entrance
US 75 left exit (really a major split, but it is signed as a left exit)

That's 22 left exits or entrances on a 15 mile long highway. Are there any other single highways with more left exits and entrances per mile?

On EB I-244, there are 4 left exits in a row (US 64-412-OK 51, LL Tisdale Parkway, Detroit Ave, and US 75/I-444).

I-84 through the Hartford, CT area has more than its share of left-lane exits.  When I first drove this road (in the late 80s) using the passing lane to get by slower traffic; I found myself having to switch lanes quite often due to those frequent left-exits.

I believe I came close to unintentionally exiting off I-84 only once at one of those exits.

Who can forget England?

Who can forget England?

Singapore, Japan and Hong Kong will all have ones with more frequent exits.

[NE2]

The West Side Highway before it collapsed was all left-side ramps.

[steviep24]

Won't set any records but the interchange of I 490 and I 390/NY 390 has left exits and entrances in all four directions. NYSDOT plans on redesigning this interchange. Not far from there I 490 has a left exit for The Inner Loop/Plymouth Ave. in Downtown Rochester.

Well, for all left entrances within a mile, little can beat the rapid-fire section of the Kennedy Expressway (I-90/94) between the Eisenhower Expressway and the Feeder Ramp.  There's 3 northbound and 3 southbound.  The overall highways do not have as much though.

[roadman65]

Considering the Pulaski Skyway in NJ as an independent freeway separate from US 1 & 9, it has two of them in its three miles of freeway. 

[1995hoo]

Inbound (northbound) I-395 in Washington, DC, feels like it has more of them than it does. I count the following in 2.1 miles beginning in Virginia just before the 14th Street Bridge:

(1) Left exit to the George Washington Memorial Parkway
(2) Left exit to US-1 (splits from I-395 after a brief concurrency over the bridge)
(3) Left-side merge as the HOV lane ends and joins the mainline
(4) Left-side entrance from Maine Avenue
(5) Left-side entrance from the Ninth Street Tunnel
* Left-side exit to I-695; I'm not sure this should count as an exit for purposes of this thread because the thru movement on I-395 is more like an exit.
(6) Left-side exit marked for C Street SW (also serves Washington Avenue, not signed as such; exit is signed for C Street and US Capitol, with several signs also listing "The House," as in the House of Representatives)

That's either 6 or 7 left-side entrances/exits in 2.1 miles depending on what you consider to be an "exit." I suppose some people might quibble with the HOV merge counting as a left-side entrance, but I count it because a lot of people coming from that lane have to cut across three lanes right away to exit for 12th Street and it contributes big-time to traffic slowdowns there.

[roadman65]

Then Tampa now with the new Crosstown Connector on I-4, the eastbound lanes have two left hand exits in two miles.  One now for the Connector at Exit 2 and the other for US 41, now a left exit at Exit 3 since the road was six laned about ten years ago.

[TheStranger]

Interstate 80 westbound from the Bay Bridge to San Francisco's South of Market area:

Exit 4: Treasure Island/Yerba Buena Island (with left-side onramp complete with stopsign, which has been set up this way since the bridge opened!)
Exit 2B: Harrison Street
Exit 2A: 5th Street

This 2-mile stretch might actually be the densest run of left exit ramps in all of California (and is the result of the bridge and approaches predating the Interstate era, as US 40/50), especially including from the eastbound side the 5th Street onramp and the Treasure Island exit.

Another contender:

Route 110 north (Arroyo Seco Parkway) near I-5 in Los Angeles:

Exit 26A: Interstate 5/Golden State Freeway north
Exit 26B: Figueroa Street/historic Route 11 & US 66

(Southbound, there's also a left exit for Hill Street just past Dodger Stadium)

One "close but not quite" example would be I-5 north between 710 and the East Los Angeles Interchange (710 north is exit 130C, but the 101/5 split is around milemarker 133 and 7th Street is exit 134C), with southbound 5 having a left-hand offramp for Route 60 plus a left-hand onramp from I-10 in all of that.

I was looking for single highways with lots of left exits. Longer highways with a bunch of left exits don't count, but posting them here is fine. So far, I-244 is ahead.

I thought it was obvious that LHD countries didn't count.

[NE2]

The 5.5-mile West Side Highway had ten southbound left-side ramps (and only one right-side).

Right-hand exits in LHD countries would though...

[Bickendan]

The 5.5-mile West Side Highway had ten southbound left-side ramps (and only one right-side).

Well that was certainly an interesting design for an expressway. Interesting to note that the Interstate grade tunnel replacement wound up getting scrapped for environmental reasons. Wonder what, exactly.

[jakeroot]

I-5 in Seattle has a few. I assume we're discounting HOV and express lane exits.

From the North:

- Entrance ramp from Ravenna (no number)
- Exit 168B towards 520
- Entrance from 520 is on the left
- Entrance from Mercer Street (exit is on right)
- Entrance from SR-599 (junction number 156)
- Exit 154A towards I-405

From the South:

- Left entrance from SR-518 (Junction number 154)
- Exit 162 for Corson Ave
- Exit 165 for Seneca
- Exit 167 for Mercer Street
- Entrance from Mercer Street

So, nowhere near I-244 or the West Side Highway, but more than normal for this area.

[Bickendan]

Hehe, Mercer. It's always an adventure driving through the Mercer Shuffle.

[jakeroot]

Hehe, Mercer. It's always an adventure driving through the Mercer Shuffle.

45th to 520 to Mercer is one of the biggest bottle necks in the state, as far as I'm concerned.

And this is fewer than the highway was originally built with, several more in that series (one every block in that section) were closed and removed a few years ago in an upgrade project.

There's a 2 mile stretch on 84 eastbound with 3 out of 4 left exits (33, 35, 36) . 4 out of 6 within 5 miles if you include 39

Then Exit 42 in West Hartford, Exit 45 (westbound only) in Hartford and 46 eastbound are some others.

[Taiwan Turnpike]

There are 3 westbound and 2 eastbound off ramps at this 4.3km (2.7 miles) stretch of  Civic Expressway,Taipei, Taiwan (known as Taipei City East-West Expy on Google Maps).

here's a map with marked exits .

I suppose that there's not enough space for right exits since there are narrow surface streets on both sides of the road.
