When someone hits the signal pole in the median, this is what is used until a new pole is installed. This one is in Long Beach, CA on Willow & Woodruff
Here they place the new pole, complete with concrete block base, on the pavement next to the dead pole and connect it, leaving it there until the next crew comes, digs out the old base and replaces it with the new one. Some intersections they often don't have time to dig the hole before the sign is taken out again, so it always is the new pole on a block, often with a dent or two on it from being a skittle.
Yeah, I've even seen them replace the pole at night too. I saw once where they couldn't replace the pole right away and had to use a portable signal since the base was bent back from the collision.
Just this year,. they had since removed the left turn signal pole, as well as all the signal poles, and placed the left turn signals on the overhead mast arms. They also added left turn signals for Woodruff.
The signal poles here are usually galvanized steel, the octagonal ones usually fall and get replaced but I've seen the MTO ones get dented on lighter impacts. The MTO poles are in sections so they usually replace the dented/broken sections and reinstall the pole.
So many street light poles on the highway get hit that they just reinstall the dented pole (giving the fact that the pole is still intact) with a new fixture. It looks sort of tacky, but it's better than wasting tax dollars on a $1000 dollar pole just so it can get hit a month later. People drive like the wold's gonna end tomorrow.
The poles on the freeways here have a breakaway coupling on the base. They look like this and they just replace the coupling (and the arm if it snaps off) and fixture when the pole gets knocked down.
And people here will hit anything near the road, road signs, large freeway signs, streetlight poles, signal poles, bus stops, guardrails are all fair game to the drivers here.
I guess that's one of the advantages of davit arms, and I guess the old stubby steel truss arms were more durable too. The aluminium tapered e arms usually snap off when the pole is knocked down.
