Additional closures will take place on the nights of the 18th, 19th, 20th & 21st. During these closures, all I-45 traffic must exit using the PR 40 exit ramps (Exit 109). Traffic will be directed across PR 40 to access IH-45 at the entrance ramps. PR 40 will be closed to traffic between the I-45 ramps. PR 40 will also be closed to westbound traffic from SH 75 to I-45. This closure is necessary to place beams & install bridge deck panels over PR 40. Message Boards have been placed advising of the closure. Detour signs and law enforcement will be placed along the detour routes to alert and guide traffic through the detour.
The construction of the 6 miles widening project, Segment 1B of IH-45 from 0.5 miles north of Vick Springs Road to 0.3 miles north of SH 19 is under way.
