The Virginia Department of Transportation and contractor Vecellio & Grogan undertook a 2 year, 37.2 million dollar project to widen Interstate 64 from four lanes to six lanes eastbound from Route 623 to Route 271 (Pouncey Tract Road) and westbound from Route 271 (Pouncey Tract Road) to Route 622. The additional through lanes will be constructed to the inside of existing I-64 in both directions. The 4.52 mile project is located in both Henrico and Goochland counties. The several miles of free-standing NCHRP-350 J-J Hooks safety barrier owned by the contractor, was manufactured by Smith-Midland.
SMC and CSS recently provided security barrier for the NATO Summit in Chicago, IL; the DNC (Democratic National Convention) in Tampa, FL; the RNC (Republican National Convention) in Charlotte, NC; and the 2013 Presidential Inauguration.
SMC was contracted by Showcall, Inc. because of our experience and expertise in concrete barrier security projects.
Teams of 7-15 people were dispatched to Chicago, Tampa, and Charlotte to manage projects whereby we rented barrier from local sources. Thirty-two SMC/CSS associates provided the supervision and labor to install over 19,000 ft. and 177 truckloads of J-J Hooks barrier.
This was SMC’s 9th consecutive inauguration in which we supplied security barrier.
In early June, an enhanced J-J Hooks barrier design was tested to MASH Test Level 3 requirements by the Texas Transportation Institute in College Station, TX. The MASH test, which supersedes NCHRP 350, uses a heavier crew cab pickup with a higher bumper. TTI performed two different anchored crash tests – bolted down (bridge decks) and pinned down (roadways).
The enhanced J-J Hooks design incorporates a longer J-Hook (18”) which mates seamlessly with the existing J-J Hooks barrier, minimum additional reinforcement (to withstand the higher impact forces transferred to the barrier when it is secured), six pockets and patented deflection limiters to reduce lateral deflection.
The successful completion of these two tests, with deflections that were less than any other tested barrier, allows J-J Hooks producers to offer highway authorities J-J Hook barrier designs for free-standing, pinned, or bolted installations.
