Map of six-laned interstates in the US?

[jeffandnicole]

An idea I had, and feel free to ignore it, would be to do something similar with toll roads. Google Maps and the like don't really mark them with any prominence, so it would be nice to have something.

I could probably do this on my own here and there as I have time, but I would want to be sure I could do something that isn't my own personal travels first.

Google Maps also tends to send people through express lanes rather than cash lanes so I'm sure people are getting unexpected bills in the mail when they were told to avoid the toll plazas.

[US 89]

US 89 is now a fully 6-lane freeway from I-15 all the way up to just short of I-84 in Davis County, UT.

UT US89 397 405

Thank you all for making such an informative and complete list and mapping.  This is a great resource.

I-94 in Kalamazoo, MI is now 6 lanes between US-131 and Sprinkle Rd.

That is already on the map on Travel Mapping. (https://travelmapping.net/user/mapview.php?units=miles&u=6lane&rg=MI)

Just noticed that the Jamboree Road freeway in Irvine (between the end of Route 261 and Barranca Parkway) is not marked yet on the 6 lane map, but from a quick Google satellite image view, is actually 8 lanes in its entire run!  (261 itself however is primarily 5 lanes, with 3 northbound and 2 southbound for much of its length)

At first glance, it doesn't look that long to me (only about two miles long). To me, pretty borderline as an addition to Travel Mapping, even if it has a little value for TM's 6lane side project.

Six-lanes is just a recipe for speeding, reckless driving and weaving.

Given equivalent traffic volumes, four lanes is a much more potent recipe for speeding, reckless driving, and weaving. Saying six lanes is worse is basically ceding the entire concept of KRETP - and even then, it's still better than cramming the same volume of traffic onto a four lane roadway.

I will say, reckless driving and weaving can exist on 6 lane, but I generally see that more when people don't understand the concept of keeping right.

It's frustrating having to switch several lanes and go lane to lane just to maintain 5-10 mph over when everyone is going the speed limit or even below in the left lanes when the right is wide open. If you're not passing anyone, move over!

That said - six lanes is far more superior than 4 lanes.

This guy is known to be against freeway expansion across the board.  He's probably happy when traffic forces everyone to go slower.

I notice you never actually bothered to refute anything I said.
