UPDATE : Work on I-40 near LR postponed

{}MAUMELLE, Ark. (AP) - Arkansas highway crews have postponed work on a portion of Interstate 40 between Little Rock and Conway because of cold weather.

{}A temporary concrete wall will be constructed Thursday night into Friday morning between the exit at Morgan and Maumelle and the Faulkner-Pulaski county line. The closure involves the westbound lane.

{}Beginning Friday night, the inside lanes in each direction will be closed overnight for about two weeks, except on Saturday and Sunday nights.

{}Work was set to start Wednesday.

{}Crews will use a wetsaw and there are concerns runoff in the cold weather could cause icy conditions.

{}Workers are widening five miles of Interstate 40 to three lanes wide in each direction - up from the current two lanes. The $21.4 million project should be completed this summer.
