Authorities are trying to curb the high number of crashes along U.S. 60 in Tempe.
Using Arizona Department of Transportation data, ABC15 found more than 1,500 accidents occurred on the highway between Rural Road and the I-10 interchange from 2014 to 2015. There were three deaths and 703 injuries.
State troopers say they're trying to reduce the danger. In September, traffic barriers were installed to prevent merging in and out of the HOV lane approaching the interchange. The area was also designated as a safety corridor.
"Speeding, weaving in and out of traffic, unsafe lane usage, following too closely to the vehicle in front of you - those are the violations we look for in those safety corridors," Trooper Kameron Lee said. "If we see it, you're going to get stopped for it."
Troopers say they're also watching the crash statistics to gauge whether their efforts are making U.S. 60 safer.
