Most traffic lights (signal heads) at a 2 road intersection? (30)

In Tampa, Florida.

This is at the intersection of Nebraska Ave. (US 41) and Fowler Ave. (SR 582), looking westbound on Fowler Ave. As you can see in this link, there are 30 traffic lights at this intersection.

Edit: I meant to specify just the signal heads, not including the pedestrian/crosswalk signals.

These are called signal "heads" if you're looking to get technical.

I'll check later, but I think we can outdo that here in Illinois.

Any wide intersection with a "signal per lane" setup is likely to have a lot. So places that space out their signals, like California, are probably out of the running.

This four-way intersection in Federal Way, WA has 32 signal heads: https://goo.gl/MYEiNs (each double left has four signal heads alone). There'd be 36 if each approach was signal-per-lane.

Jesus H...yeah, I don't think I've ever seen anything that crazy here in New York. That many lanes and NYSDOT starts spacing stuff out. Most I can remember seeing in this state is 20 + 8 ped heads.

I wish I was able to get photos (drove it only at night), but I passed through several intersections along The Strip in Las Vegas that had very impressive amounts of signals. The intersection with Harmon Avenue, in particular, has 52 separate traffic signal heads. However, there are so many, that I could be off by one or two.

Here are some from Illinois:

Six Corners, Joliet: 30 signal heads for vehicles, 12 for pedestrians, total of 42.
Meacham & Golf, Schaumburg: 24 signal heads for vehicles, 16 for pedestrians, total of 40.

IDOT requires two signals per turning movement and a minimum of three signals for the through movement.

That is absolutely ridiculous. Like...WHY? Duplicated heads for one movement? We would have made do with half as many heads in NY, if not fewer. :spin:

Randall Road at Fabyian Parkway in Kane County, Illinois, has a good number

If we can count intersections with a railroad crossing but not count the pre-signals, US 14 at New Wilke Road also has a good number (however it appears the Streetview van has not been through there since the rebuild of the intersection wrapped up).

Or how about the IL 83 at IL 137?

Yeah, I meant to specify that. I changed the title accordingly.

And I was just in Las Vegas a little over a month ago. Somehow it slipped my mind a little. But with all the vehicular traffic, pedestrian traffic, and tall lit-up buildings on that road, I can kinda understand the excessiveness.

Revive 755

WI 100/Mayfair Road at US 18/Bluemound Road in the Milwaukee area has at least 31 vehicular signal heads and 15 +/- pedestrian signal heads for a total of 46.


Since Illinois does not do head per lane in Chicagoland (excluding Kane County, Naperville, and Will County on occasion), I don't think Illinois will be able to top the Las Vegas intersection.

First, note that new signal standards for Nevada typically specify one overhead signal head per lane, plus a far side pole mount for through and left turn signals. For larger intersections, it's becoming increasingly common to include supplemental signals on the near side as well (pole mount for the through, and overhead on the opposing mast arm for left turns). That automatically increases the signal head count.

This intersection presents additional challenges. It is one of the main entrances to the City Center complex, located on a wider part of Las Vegas Blvd (triple left turns and four through lanes) and an unusually wide part of Harmon Avenue (dual left turns and 3/4 through lanes). Also, Harmon Ave intersects at an angle, due to how the original eastern alignment had to be curved to tie into City Center. The width and angle of the intersecting streets creates sa very big intersection and results in typical placement of most signal heads (on mast arms or far right/left poles across from the stop bar) being way beyond the longitudinal distance specified and/or outside the "cone of vision" lateral offsets specified in the MUTCD. This explains the why three of the four approaches have redundant signal mast arms.


BTW: I counted 53 signal heads.

Looks like there is a programmed delay for some of the left turn heads?  In the Streetview photos, the far head for the triple lefts still has a green arrow while the primary and median mounted head have yellow arrows and later red arrows.  I don't believe I've seen that elsewhere.

It's very possible there's a delay there, given the width of the intersection. I've seen that in a few places with wide intersections where the main signal is no longer visible once you've crossed a little past the stop line. Mostly at some major SPUIs.

26 signal heads + 4 pedestrian signal heads at the intersection of Waxpool Rd (SR-625) and Loudoun County Pkwy (SR-607) near Ashburn.

This may win it for Virginia, or at least in the Northern Virginia region where signals are generally placed between lanes instead of directly over lanes and supplemental side-mounted or near-side signals are rare. There could be some intersections in the Richmond suburbs (US-250 near Short Pump) and Charlottesville (US-29 north of Charlottesville) that could surpass this, since there is usually a signal head per lane.

I'll have to check around myself but I know of one intersection in Hampton that definitely has it beat

https://goo.gl/maps/5BYAu7i1f5F2

This is Mercury Blvd & Armistead Ave (where VA 134 leaves Armistead to join US 258). You'll have to move around to see all the heads (they're black and several of them are ground mounted)

I counted 32 heads + 6 pedestrian signals

I don't think there's any other intersection in the country that tops this.  This one has 0 pedestrian signals too.  :)

Take the road less traveled.

That's the same intersection in Vegas from Ian's post above (rotate the camera 180 degrees).

Dusting off this thread . . .

While it won't top the Las Vegas intersection, Eagle Road at Pine Road in Meridan, Idaho has around 30 vehicular heads and 4 pedestrian heads for a total of at least 34.
