The delineators on Highway 14 between Nicollet and North Mankato were removed late Tuesday afternoon after they began to fail. Motorists are reminded that the roadway remains a no-passing zone. The roadway is signed accordingly.
The delineators, which are hollow, yellow plastic tubes, began to fail in the extreme heat of Tuesday at approximately 3 p.m. Highway crews were immediately called to remove all the delineators and retrieve any that had blown away, according to Rebecca Arndt, District 7 Minnesota Department of Transportation Public Information Officer. No vehicles were harmed.
The failure may be due to a combination of extreme heat, which hit record highs of nearly 100 degrees on Tuesday afternoon, strong winds and the fresh pavement in which the delineators were placed. MnDOT officials will investigate the cause of the failure. The delineators will not be replaced until the investigation is complete.
Traffic will be monitored closely on that stretch of Highway 14, Arndt said, repeating that motorists should be aware that it continues to be a no passing zone.
