A project on I 75 in Whitley and Laurel Counties during the 1986 construction season involved numerous lane closures associated with spot pavement replacement and joint sealing. Traffic congestion associated with heavy volumes and late merges resulted in the use of the following traffic control devices to supplement standard lane closure devices; (1) variable message signs, (2) supplemental lane closure warning signs, and (3) rumble strips placed in the lane to be closed in advance of the taper. Recommendations from the study included the following: (1) supplemental signs for all long-term closures in high-volume, high-speed, four-lane roadways; (2) variable message signs when one-way hourly volumes exceed 1,000; and, (3) application of rumble strips when other devices do not reduce late merges and there is excessive congestion.
