    A practice used during long-term construction activities on divided highways is to allow two-lane, two-way traffic operations (TLTWO) on one roadway while the other roadway is completely closed to traffic. Federal, state, and local officials have become increasingly concerned in recent years about safety problems in TLTWO work zones. This report presents the results of operational and accident studies of 36 construction sites employing either two-lane, two-way operations or lane closure traffic control. Project cost information for four TLTWO and ten lane closure sites was also analyzed. Results of the study were divided into four areas: evaluation of centerline treatments on the two-way roadway segment; design of temporary median crossover roadways; comparison of TLTWO and lane closure operations; and general results.
