While shoulder rumble strips have historically been installed on rural freeways, I think some states are now adding them to select urban freeways as well (especially those with high amounts of run off the road crashes), since there have been studies that they can be just as effective on urban freeways as they are on rural freeways. Historically most states did not use them on urban freeways due to the issue of noise complaints especially at night.
I would like to know, does anyone know examples of such states that have shoulder rumble strips on select urban highways? On which highways?
Illinois has them on both the urban tollways and freeways. Indiana also uses them on the Borman Expressway (I-80/94).

ODOT uses them in Columbus on I-70 east of I-71.
NYSTA puts rumble strips everywhere, including on ramps and along I-190 in Buffalo and I-87 in Yonkers, yet NYSDOT tends to restrict them to less-developed sections of cities, suburban and rural areas. This is especially notable along I-87 in the Bronx at the change in jurisdiction between NYSDOT and NYSTA (only the latter has rumble strips). However, sections of the NYSDOT-maintained Bruckner, Throgs Neck and Cross Bronx Expressways feature rumble strips in the SE Bronx (east of the Hutch/I-678)
Rumble strips have been installed on some of the more recently resurfaced freeways in the Detroit area.
Massachusetts provides shoulder rumble strips on all freeways, both in urban and rural areas.
NJ has them on all freeway/highways, both urban & rural.
They have them on the shoulders on some non-limited access roads as well. And they are now adding center-strip rumble strips also.

Massachusetts has center rumble strips on certain super twos that have had a high rate of heard-on crashes
Pennsylvania has them on most freeways and are adding them to surface roads as well. Where I live most of the SRs have them on the median.
Texas has them in many areas: most freeways, some highways, even some FM/RM two-lane roads. I don't recall having found any in the center median, but there are a lot of highways that I would recommend. Nothing like two-way traffic at 65 or 70 mph separated by nothing but a double yellow line.
For states that use rumble strips on the center line, do they just use them on double-line (no passing) zones, or in both passing/non-passing zones?
NJ is using them in both passing and non-passing zones.

Likewise in Illinois and Michigan, both passing ans no-passing zones.
Arizona also uses centerline rumble strips for both passing and no passing zones as well.

In PA just no passing from what I've seen but they do use them in the center left turn lanes. I guess that makes sense as well.
They're a "matter of policy" in Washington State, meaning that urban freeways can have them, but only if it's proven to be worth the money. For example, on our freeways with Ontario tall walls/Jersey barriers in the center and noise walls on the shoulder, there's no point, since there's no risk of running off the road. But in places like Puyallup (basically urban), along WA-512, where only grass and an occasional guardrail separates traffic flow, the inside shoulder has rumble strips (though weirdly, the unprotected outer shoulder has nothing, despite large embankments along most of the route -- I assume the "matter of policy" approach has dictated that the lack of crashes from people leaving the roadway towards the outer edge means that putting them in along the shoulder would be a waste of money).
Where NY uses centerline rumble strips, they're in passing zones as well.
Nevada does not use rumble strips on urban freeways.

This is delving from urban freeways topic... But Nevada uses both edge and center lines on most rural highways that see any appreciable amount of traffic. The rumble stripes are continuous through the safety zone and only stop at intersections or driveways. Nevada now puts center and edge rumble strips directly under the paint stripe.
Every freeway I've seen in Florida has them
