Accidents on eastbound N.M. 502 and northbound N.M. 4 brought rush hour traffic to a standstill Wednesday afternoon.
N.M. 502 traffic was backed up nearly to 15th Street. Northbound traffic on N.M. 4 was stopped beyond White Rock. Commuters faced delays of 40 minutes to more than an hour.
During the 5–6 p.m. peak, it took a half hour to move from 15th Street to DP Road.
As of 6 p.m. Wednesday evening, officers on the scene had not finalized their investigations, but Cpl. Doug Ehler of the Los Alamos Police Department provided preliminary reports, but rain-slick streets may have been a contributing factor.
