Narrowest roads that are marked with two or more lanes

[Chris19001]

Here's one in Philly.  There aren't trucks, which is good.  But this is darn narrow going northbound (right side of street view) since the last repaving and restriping.

Yikes, that is narrow. That bridge in the background is also in the running for highest overpasses.

What is the narrowest well marked signed route?

Also the access road form US-60 to Mud River Baptist Church in Barboursville, WV, which has 9' lanes.

9-foot lanes are relatively common across WV's route network, even on some primary roads.

The Burlington—Bristol Bridge (which carries PA/NJ 413 over the Delaware River) is pretty narrow. Until a repave about 5-6 years ago, it was only striped with a single yellow line.

Market Street Bridge in Harrisburg provides four 10 ft lanes with no center divider. 40 mph speed limit.

Front Street in Downtown Harrisburg has three 10 ft lanes with curbs. 35 mph speed limit.

In uptown Harrisburg, Front Street has four lanes... that are 9 ft. Same 35 mph speed limit.

From experience driving Front Street, it wasn't a problem. If anything, the speed limit could have been 40 or 45.

Absolutely not... I frequently go down Front Street and get pretty uncomfortable if I'm in the center lane. The curve at Liberty Street and the dip in front of UPMC is straight up dangerous if traffic is heavy. It gets even worse on the north end of the city when it becomes two lanes each way undivided.

I'd rather break down in Allison Hill than take Front Street during rush hour!

Both of those bridges have 20-foot decks, FYI.

Lumpkin Street in Athens, GA used to have four 7' lanes with no median or center turning lane from downtown to Five Points. Buses couldn't even fit into a single lane. Athens-Clarke County has reconstructed it since then, and now it has two 10' lanes with two bike lanes and a center turning lane -- and they had to widen it to do so.

The Grand Island bridges on I-190 between Buffalo and Niagara Falls have the least margin for error of any multi-lane bridge I've ever been on. A true nail-biter for first time drivers!

You didn't even mention the scariest part: they used to be reversible lanes! Engine driving on one of those bridges with oncoming traffic!

Also, I'm pretty sure most older tunnels could qualify for this thread.

Any idea if there are pictures of this old setup? Looks like the conversion took place in the mid-2000s, and isn't on Street View.

7' lanes seem wicked narrow for an urban setup. Farm road? Sure, but even urban roads typically bottom out around 8' or so. 7' is nuts.
