>Narrowest< medians you know of?

[ukfan758]

The section of I-64 (concurrent with US 60 and US 220) between Covington and Clifton Forge, Va. For years there was nothing there. Virginia finally got around to installing guardrail and/or cable barrier a few years ago.

On Kentucky's parkway system, the Western Kentucky Parkway has a much narrower grass median than any other interstate, parkway or expressway in the state.

I would nominate I-264 north of Westport Road, parts of it look quite narrow and still does not have a barrier in the middle. https://www.google.com/maps/place/Louisville,+KY/@38.2729434,-85.6294376,3a,75y,235.7h,89.25t/data=!3m4!1e1!3m2!1sJoiukrYHCTRfZElNd09nGg!2e0!4m2!3m1!1s0x88690b1ab35bd511:0xd4d3b4282071fd32

15-foot-wide median.

Two lines of high-tension cable guardrail, which is strong enough to turn a truck at up to about a 20 degree impact angle at highway speed.

Alleghany County - Interstate 64 Median Barrier Cable Project
http://www.virginiadot.org/projects/staunton/alleghany_county_-_interstate_64__cable.asp

"This project extends from mile post 7.3 to mile post 16.5.  The project will install high tension wire rope (cable barrier)."

"The purpose is to reduce median crossover crashes along this section of I-64 with a narrow median.  The section of narrow median runs from mile post 7.3 to mile post 16.5 between Exit 7 and Exit 16 and has an average daily traffic count of 11,000 with 23% trucks according to 2009 traffic data.  There are two interchanges that fall within the project limits, Exit 10 and Exit 14."

Completed in 2012.

RI 78 just has a concrete barrier in the median.

Do the grass medians on Oklahoma turnpikes that haven't been upgraded to concrete or cable barriers count? 75mph speed limits with no inside shoulder and nothing but 12-14' of grass on level ground separating you from a head-on collision.

US-24 (Telegraph Road) at M-10/I-696 in Southfield MI.

Narrowest, not sure, but the rail on the 9A/100 freeway section in Westchester County NY was hella narrow at one point and I traumatized myself after hitting it while still learning to drive.
