States with mountainous terrain frequently have ‘dead man curves’. US Hwy 50 in Colorado has two such curves paral-leling the Arkansas River. In the past, the canyon corridor between mile markers 230-231 averaged three truck rollovers annually. Spillage from the truck’s fuel combined with hazardous cargo took weeks or months to clean up. Cars consistently damaged the guardrail and replacement was frequent. In one area the drop-off is 80 feet. Colorado DOT installed stronger 3-rib, more deeply anchored guardrails, but the hazard still existed.

Acr3852269359556011746Border and port moni-toring is vital to Amer-ica’s security. In Sep-tember ’05 a Homeland Security Grant was is-sued to the TxDOT of-fice in Corpus Christi, Texas. The funding was used to increase port security by moni-toring all ferry and ve-hicular traffic traveling from the mainland to the City of Port Aran-sas/Mustang Island. Normally a 45 minute drive, the ferry ride is less than 10 minutes. Additionally, all cargo ships are observed to ensure that the “float-ing roadway” stays open/has no problems. This is critical with two naval bases close by.

TxDOT More Efficient With Wireless Overheight Truck Detection

Overheight Truck Detection The Yoakum District TxDOT Office was responsible for maintaining the “ding-a-ling” over height truck warning system in Columbus, TX, on Interstate 10 between San Antonio and Houston.

In theory, if you hit the tubes, you’ll hit the overpass. According to Randy Zimmerman, Traffic Shop Supervisor, the line “was always sagging, so a bucket truck was dispatched monthly to adjust the cable holding the ding-a-lings” to maintain the proper height. This work was in addition to re-hanging the cable if an over height load snagged the cable and tore the system down.
