In addition, the signal operations should return to normal late Monday and will significantly reduce delays currently experienced at the intersection.
For the early part on Monday, detours may still be in effect. Traffic will be detoured onto 58th Ave. W and 54th Ave. W for traffic on 236th St. SW; traffic will be detoured onto 237th St. SW and 235th St. SW for traffic travelling on 56th Ave. W. Alternate travel routes are strongly advised. Drivers should expect significant traffic delays during construction.
Businesses near this intersection will remain accessible and we encourage the community to continue to visit them during this time.
The top-most asphalt layer will be paved when warmer spring weather arrives. Work by the city’s contractor and utility companies is expected to continue throughout the fall and winter along roadway shoulders and not impact traffic.
