Crews are expected to stripe eastbound (EB) Dyer Road underneath the freeway to reopen the street to three lanes, which will require closing EB Dyer from 9 p.m., Friday, Aug. 14 to 5 a.m., Saturday, Aug. 15.

Once striping work at Dyer is complete, crews will place concrete barriers along eastbound and westbound MacArthur Boulevard on the east side of the bridge to shift traffic towards the outside and reduce the street to two lanes in each direction. This will allow crews to safely perform work in the median.
