Intersections: 22 a. Keep intersections open to traffic at all times, except when paving or planing I 23 operations through an intersection requires closure. Such closure must be kept 24 to the minimum time required to place and compact the HMA mixture, or plane 25 as appropriate. For paving, schedule such closure to individual lanes or portions I 26 thereof that allows the traffic volumes and schedule of traffic volumes required in 27 the approved traffic control plan. Schedule work so that adjacent intersections 28 are not impacted at the same time and comply with the traffic control restrictions I 29 required by the Traffic Engineer. Each individual intersection closure or partial 30 closure, must be addressed in the traffic control plan, which must be submitted 31 to and accepted by the Engineer, see Section 1-10.2(2). I 32 b.
