Any large intersections?

[ColossalBlocks]

I am talking about intersections with 2 or more turn lanes.

[hotdogPi]

You already asked that question in another thread.

[NE2]

No.

2 or more turn lanes? I could post probably a few dozen of those just from Ada County. None of them are particularly impressive though, not going to bother.

Are these rare in southeast Missouri? I can think of many within 10 miles of me. Granted I live northwest of Boston, but still, not a rarity.

They're all over the place in Maryland, Virginia and North Carolina

Does turning straight count?

Plenty in Huntsville, along with a lot of Alabama. Just a few examples:

And that's only just scratching the surface.

This one in Joliet, IL comes to mind for me...

And this one further NW on US 30, near where I grew up...

Never thought of Six Corners or the other six corners at Caton Farm & Gaylord as really big intersections, as there's only one turn lane at each.  Now this one was small, and has recently become a very big intersection with dual left turn lanes in each direction: https://goo.gl/maps/QuPQApjKsMR2

Could just be me, because growing up I remember crossing rt 30 to get to the 7-11 on the other side. It was plenty big to me as a 15 year old.

Of course 30 was 2 laned then.  They really should have upgraded that whole stretch from 55 to Larkin Ave to a 4 laned road soon after the Louis Joliet Mall opened.

As for the Weber Rd. Renwick intersection, I'm glad they got that done.  I take that into work when there's backups on 55.

As usual, IDOT was 30 years behind.

Just a little side note here.... those traffic signals are SUPER UGLY!!!!

Does turning straight count?

This is the intersection of Tassajara Road and Dublin Blvd in Dublin, California.

Two of the approaches have triple left turn lanes, and two of the approaches have double left turn lanes and double right turn lanes.

The east side of the intersection is not completed and will allow for additional lanes to be added.  At full build out each leg of the intersection will have seven approach lanes and three departure lanes.




Tasman Drive and Zanker Road in San Jose doesn't have as many turn lanes, but due to the triple light rail tracks in the center median make for a rather long trip across the intersection.

I am talking about intersections with 2 or more turn lanes.

The intersections in Las Vegas between Las Vegas Blvd with Flamingo Blvd and Tropicana Ave (and perhaps other points south, I haven't looked lately) are so massive that pedestrian walkways have been constructed. Three left and two right turn lanes as well as several through lanes in all four directions at both intersections, if memory serves.

There not rare but not common either.

The ped walkways were constructed due to the massive amount of pedestrians crossing, not because of the distance. 

There are several other intersections with crossings as well along the Strip.

Ehh, Caltrans will always be big.

Three left and two right turn lanes as well as several through lanes in all four directions at both intersections, if memory serves.

At Las Vegas Blvd & Flamingo Road, there are no triple left turn lanes at all, and the only double right turn is eastbound Flamingo to southbound LV Blvd.

At Las Vegas Blvd & Tropicana Ave, there are only triple left turns on northbound and southbound Las Vegas Blvd. There are no double right turns either. However, Tropicana does have double lefts, dedicated right turn lanes, and four through lanes here.

You will find triple left turn lanes at many other locations along Las Vegas Blvd though. These are primarily at entrances to the resorts (and primarily exist, I believe, because there was insufficient right of way for the storage needed if double left turn lanes were used).

The ped walkways were constructed due to the massive amount of pedestrians crossing, not because of the distance.

Correct. The wide intersection of Tropicana Ave & Las Vegas Blvd, with high levels of pedestrian/driver inattention, had the highest pedestrian fatality rate in the state for multiple years. Add to that the way pedestrians/tourists tend to not obey ped crossing signals, this intersection experienced significant travel time delays.

Las Vegas Blvd & Tropicana Ave was the first to have pedestrian crossing walkways constructed. These were constructed by NDOT, which still had jurisdiction over Las Vegas Blvd at the time (and still does in the vicinity of this intersection). Las Vegas Blvd & Flamingo Road was next, with two crossings being built concurrently with construction of the Bellagio and the other two coming later. Pedestrian crossings at Spring Mountain Road and at Harmon Ave intersections have since been constructed.
