I find it funny how since it near the airport the high masts are so short

i Think its Law for Roadway Lighting to be Short near Airports....so the Pilots don't Confuse the Roadway Lights for the Runway Lights.

Yes it is, also so they dont get hit

in Shreveport,Louisiana near the Airport the Cobraheads on Tall Poles suddenly turn into wallpack Fixtures on Short Poles.

On other roads they use tiny 100 watt shoe boxes on 15 foot poles, those are right at the end of the runway!

iv'e Never seen a Shoebox smaller than 250 Watts....most i see are 400 or 1 KW.

Well there spaced very close together, they light the same roads that usually use 400 watt HPS cobras.

That High mast isn't really high. Its shorter than the Poles with the cobraheads on them! xD

Not really look at the poles in the background, the hight mast is about 60-70 feet tall, the shortest they get is 50 (kind of pointless) and they go up to 200 feet! I might try to get about a cobra head or two from this site, I would really like a M400R2 and M400A (the new style) both in 400 watt HPS (I might have to settle for 250)

I wouldn't mind an M-400A. Could you get one for me? =3

I just would like to save one of those truss arms in the background and maybe a smallish fixture.

I'll be giving them a call on Monday to see what I can arrange

Cool thanks

OK update, I got through to them and.... the lights wont come down until January 2011 So we`ll see then.
UPDATE: Its now March or April
SECOND UPDATE: And now its some time this year, I don't know when

Yeah I went by these today and they're still up, although some more highmast lights have been put up.

I remember when they redid the lighting on the 427 they put up the highmasts in 05-06 but they left the old cobraheads and poles up until March 09

Hmm. Right near the airport runways we just don't have streetlights.

They aren't that close here, it is about about a mile and a half until the runway starts from where this is. Here the poles at the end of runways are very short!

Hmm. Since this is near an airport thoguh, you'd think they'd install cobraheads to replace highmasts instead of the other way around though. I don't really live to far away from T.F. Green Airport in Warwick. I'm close to everything in central RI.

Update: these lights have also been removed, in fact there's only a couple "truss" type poles left standing in this interchange, both hold R47s IIRC. They started removing the lights on the ramps and overpasses earlier this year and now almost all the old poles are gone.

Here's how we light our sections of freeway that are close to the runway.

Interestingly because of how close to the airport this section of freeway is, they swapped out out some of the original 40-50ft truss poles with shorter ones during the mid 90s...sometime around '96 if I remember correctly.

All the older poles here were/are about 25ft tall. The newer davits for relay installations i'd guess to be around 30-35ft.I think the tall davits were started in the 80s here with 400W HPS Cooper OVM (M-400R2 for spot replacement). The older style short davits with the long arms were still used on the ramps though and lights were installed in the jersy barrier on the freeway. Now lights are installed along the right sholders. The poles today are around the same height as those from the 80s on the highway. The ramp poles are a tad shorter than the old style davits that were used here and the arm is much shorter (about 4ft). Ironically, new versions of the "old style" davits are still used to replace knockdowns. The truss arms used here in the 60s and 70s are still used for new installations and replacements for lights that have individual PCs (AKA they're owned by NGrid and leased to RIDOT).
