Mini Freeways

[Dirt Roads]

From West Virginia:

Clarksburg Freeway (US-50)
Oak Hill Expressway (originally US-21, now US-19)
Jennings Randolph Bridge freeway (US-30, crossing from Chester -to- East Liverpool OH)
WV-9 (Shenandoah Junction -to- East Martinsburg)

perhaps there are more...

oops... The US-250 freeway in Wheeling doesn't count.

[kphoger]

Oh yeah, one more, Expressway Street in Council Bluffs. Technically it has no interchanges, but it goes onto an elevated bridge with a speed limit of 45 over an industrial area.

That's an interesting one.

First thing I thought of was WI-11 around Monroe. It's a true freeway but it's short and doesn't connect to anything besides 2 lane roads.

First thing I thought of was WI-11 around Monroe. It's a true freeway but it's short and doesn't connect to anything besides 2 lane roads.

I thought that was weird the one time I drove through it.

It does have that recreational trail crossing between two exits though:


But I think there are other places with trails crossing a freeway (or a roadway close to that). I think there's another one on the Palisades Interstate Parkway in either New Jersey or New York.

It was part of a larger plan to have a four lane WI-11 connect to I-39/90 that never happened.

[webny99]

There's also a short stretch of US 1 freeway in Maine between Brunswick and Bath.

I find it strange that it's not connected to I-295, but it doesn't, so it does qualify.

Connect to modern-day I-39/90 AND continue the freeway eastward to feed into modern day I-43 at the curve on the NW corner of the Clinton, WI area instead of the then WI 15 freeway continuing southwestward to Beloit.

There is a similar at grade recreational trail crossing (WIOUWASH State Trail, also an abandoned railroad grade) on WI 29 on the north edge of Wittenberg, WI.

We have 5 legit mini freeways in the Chicago area. However, all 5 do have some kind of interchange with an Interstate.

IL Route 38 (Roosevelt Rd) is a freeway between I-294 and Route 83. Only section of Roosevelt Rd that is posted 55.
https://www.google.com/maps/@41.8632767,-87.9397505,15.5z

IL Route 83 (Kingery Hwy) is a freeway between I-88 and 55th St. However there is one street (Oakmont Dr) that has a RI-RO situation with Southbound 83.
https://www.google.com/maps/@41.819563,-87.9536996,13.5z

IL Route 171 (1st Ave) is a freeway between 55th St and 44th St. 3 interchanges (I-55, Joliet Rd, 47th St) with a stop light on each end before 171 becomes an arterial street. https://www.google.com/maps/@41.8029318,-87.8284857,15z

IL Route 394 is the extension of the Bishop Ford Freeway from I-80/94/294 to Sauk Trail where that is a stoplight. There are 2 interchanges (Glenwood-Dyer Rd, US 30 Lincoln Hwy). https://www.google.com/maps/@41.5372469,-87.6147983,13z

There is a mini freeway for Stony Island Ave off I-94. It does have an interchange at 103rd St.
https://www.google.com/maps/@41.7117001,-87.5919712,14.75z

Ohio Street is another mini freeway off I-90/I-94. It and Stony Island Avenue were planned termini for the aborted I-694, which was to be a freeway version of Lake Shore Drive.

[jp the roadgeek]

The ultimate one that comes to mind is the US 6 Willimantic bypass that was once slated to become part of I-84 to Providence.  No connection to anything whatsoever.  There's also the RI 138 freeway between US 1 and Newport. 

[GCrites]

I would not include the OP's example of Harshman Avenue in Riverside OH because it only has the one interchange.  That's qualifies as a "One Exit Wonder".

It has interchanges with both Springfield Street and OH-4.

With two at-grade intersections in between the them.  And the interchange with OH-4 is only free-flowing for OH-4:  Hershman has stoplights there.

Ah I get it now, no stoplights even if they are on interchanges.

[Concrete Bob]

In Sacramento, Watt Avenue between Fair Oaks Boulevard and US 50 has two consecutive interchanges at American River Drive and La Riviera Drive.  US 50 and Watt Avenue used to have a full cloverleaf interchange, until it was upgraded to a parclo in 2012 or so. 

[nexus73]

19th Avenue in Eugene OR has a short stretch of freeway which is in the area of Lane Community College.  The freeway section connects with regular surface streets on each end.  It appears to have been planned to be part of a beltway that was only completed going through north Eugene.

[US 89]

In Utah, we have:

US 6/191 in Price - super two bypass
US 89, Antelope Drive to I-84 - interchange at 84 is a weird parclo thing that's supposed to become a SPUI soon
SR 7 (Southern Parkway) in St George - interchange at I-15 is a SPUI with no free flow between the two roads
SR 154 (Bangerter Highway), I-15 to 2700 West - same deal, SPUI at I-15 (what's with these?)
SR 154, 13400 South to 4700 South

US 40 from I-80 to SR 32 is similar with a SPUI at 80, but it does have a couple of free flow ramps for the highest traffic movements

[1995hoo]

The stretch of road that most readily comes to mind for me is a short segment, about 1.5 miles, of US-50 (Arlington Boulevard) here in Fairfax County from just west of Gallows Road to just west of Jaguar Trail. In between those points, it has three interchanges and it feels like a high-speed road despite having traffic lights, and becoming a much narrower surface arterial, to either side of that segment. My father always thought the person who laid out the interchange with the Beltway was drunk when he designed it.

CA 1 has two mini freeways:

• CA 156 to Carmel. CA 156 becomes a freeway right as it ends with CA 1 and before that is a Super-2 from US 101.
• Through Morro Bay, it has a few interchanges
• The freeway section from Pacifica doesn't count because CA 1 has a concurrency with I-280 at Daly City

The Westside Parkway, or CA-58 is still not connected to CA 99, but it should happen in the 2-3 years!
CA 198 is a freeway through the city of Hanford but downgrades to expressway before CA 99.
CA 20 is the only freeway through Grass Valley and Nevada City
CA 29 is a freeway through the city of Lakeport
US 101 is a freeway through Ukiah

[thspfc]

Maybe US-93 in Missoula: https://www.google.com/maps/@46.9000375,-114.0380041,1050m/data=!3m1!1e3

I suppose the Great Highway of the Republic (I-180 in Wyoming) qualifies.

[Skye]

In Ohio, US 27 becomes a Freeway a short distance north of I-275 and ends north of OH 128

[ztonyg]

Arizona:

AZ 210 (Aviation Highway) is a mini-freeway from Broadway Rd. to just S of 22nd St. and again from Dodge Blvd. to Golf Links Rd. in Tucson
AZ 153 used to be a mini-freeway from University Dr. to Washington St. in Phoenix (but now the mini freeway is from University Dr. to Sky Harbor Blvd.)
Fain Rd. / Pioneer Pkwy. (US 89A) has some long "mini-freeway" segments around Prescott / Prescott Valley

More from Oregon:
OR 18/22 east of Grand Ronde to Valley Junction (OR 18/18B/22 interchange)

OR 22, from OR 99W/223 to roughly OR 51, and again along the Willamette through West Salem into downtown Salem.

US 97 through Bend, and on a super2/4 basis for Klamath Falls and Redmond.

And speaking of super-2s and 4s, US 101 gets a few between Leggit and Eureka, signed with Freeway Entrance signs, though they can be on the longer side.

A segment of VA 150 extending from Parham Road in Henrico County to VA 147 in the City of Richmond is an isolated freeway segment with no other freeway connections. VA 150 becomes a surface arterial for a little over a mile between VA 147 and Forest Hill Avenue before becoming a freeway again.

The Harvey Taylor Bridge Bypass in Camp Hill, PA is a 50 MPH expressway born out of Forster St in Harrisburg as well as the eponymous bridge. From east to west, it has one RIRO interchange utilizing a few of Wormleysburg's residential streets, one folded diamond with Erford Rd, and then proceeds to collide with US 11/15 in a spectacular mess of crisscrossing ramps, lanes, 3M traffic lights, and stop signs.

10th Avenue in Altoona, PA sometimes seems to be referred to as the 10th Avenue Expressway, or P R R Expressway since it runs shoulder-to-shoulder with Pennsylvania Railroad tracks. In actuality, it is a 40 MPH 3-lane one-way street that only goes westbound, with no eastbound side, and has cloverleaf ramps connecting to 17th Street and 18th Street. After a final ramp curving to form 19th Street, 10th Avenue becomes a backwoods alley before petering out at 24 1/2 street.

US 322 and PA 72 team up to form a half-mile long expressway south of Lebanon and Quentin, before going their separate ways. It manages to have one folded diamond interchange with Ironmaster Rd.

There's also a short stretch of US 1 freeway in Maine between Brunswick and Bath.

I find it strange that it's not connected to I-295, but it doesn't, so it does qualify.

I recall seeing a 95 shield on that stretch, near where 295 is now but that was in 1997. Was 95 supposed to go closer to the coast?

CA 77 fits this thread perfectly:

https://www.gribblenation.org/2019/02/california-state-route-77-real-shortest.html?m=1

Nothing quite as short as CASR-77, but there are freeway sections of both CASR-1 and US-101 in California that don't connect to any other freeways. Now, both of those ROUTES eventually connect to other freeways, but several freeway portions do not.

Watt Avenue, Howe Avenue, and Sunrise Bvld in Sacramento County all have short freeway portions (along with, in some cases, designated freeway sections further out that haven't been built as freeway), but all connect to US-50.

[3467]

Several on 34 in Iowa. Burlington stretches into Illinois .Bypasses of My Pleasant Fairfield and Ottumwa. Also Knoxville bypass. As well as Oskaloosa Pella Monroe And 27 Mason City? Charles City Waverly Iowa City and Donnelson.

The Watt section:
Two interchanges (La Riviera Drive, American River Drive); prior to about 2010-2011, there was a cloverleaf with US 50 itself.

https://www.google.com/maps/place/Sacramento,+CA+95826/@38.5644026,-121.3846691,16z/data=!4m5!3m4!1s0x809ac4cac6626f59:0xd5574d7ea6648b2a!8m2!3d38.5499634!4d-121.3884671

The overpasses of Watt above La Riviera and American River Drive are due to Watt crossing the American River itself.  IIRC this was all built as part of the US 50 freeway project, with the section of Watt from US 50 to Jackson Road (so south of the mini-freeway) originally proposed as a Route 16 reroute that never happened.

Howe has one interchange with La Riviera northbound past US 50 but I don't think this really counts as a mini-freeway as there are no other interchanges after.

Sunrise doesn't appear to be a mini-freeway at all.
