Mobile and short term stationary road maintenance operations produce some of the biggest headaches for work zone safety. You want to protect crews and the traveling public and stay efficient too. A handy new booklet, Work Zone Safety: Guidelines for Construction, Maintenance, and Utility Operations, just published by the T.I.C. and WisDOT, can help. Based on the MUTCD and modified to reflect Wisconsin practices, it shows how to lay out traffic control for work zones in a variety of common situations. The booklet emphasizes short term work sites and gives explicit guidelines for mobile operations. It also provides guidance for short duration operations which can last up to an hour. More than 30 readable diagrams show work zone signing and setup for shoulder work, lane closures, and intersection projects for various traffic speeds and highway types.
