</span>How often do street lights get moved? I guess the ones around my<br>
house are there for like 30-50years ...<br></blockquote><div><br></div><div>For the ones on the MLK Expressway in Tulsa, we're currently averaging closer to 3-5 years, with a currently pending roadworks project currently moving lampposts from unprotected positions on the outfields to protected positions on the center divider or unprotected on the infield median. This was most likely done to improve safety for motorists and reduce vandalism. The former positions were quite close to the pavement and were frequently downed by wayward vehicles that left the roadway and were prone to metal theft, including at least one particularly adventurous metal thief intentionally running down a lamppost, who was caught cutting up the post to haul away.</div><div><br></div><div>But, my region is rather unique in general when it comes to moving stuff around that's typically static; since I moved here, OklaDOT moved a ~2 mile segment of I 44 one block south, and moved a ~3 mile segment of Interstate 40 roughly 5 blocks south in Oklahoma City, plus various other more minor (2-lane) state highways built on broad right of ways have moved from one side of the right of way to the other. Though in the 2-lane cases, they're positioned in the right-of-way as if one half of a dual carriageway, and when they repaved it, they literally built a new highway where the other carriageway would go, then removed the original (OK 99 in Osage County and various segments of OK 33 between OK 48 and OK 8, and particularly between I 35 and OK 8 are prone to having ruins of the old roadways still partially intact, though really any two-lane state highway might have this in a few places).</div></div></div></div>
