This marks the latest in a series of collisions between trucks and the downtown core's low-clearance rail bridges. A similar incident occurred last month when a truck became stuck beneath a rail bridge at 1 Street S.E.—two blocks east of Tuesday's collision. That same bridge was involved in an earlier collision in August, resulting in a fine for the driver. The recurring pattern suggests the downtown's low-clearance rail infrastructure remains a persistent hazard for commercial vehicles.
Will the city implement additional warnings or height-restriction signage at this and other low-clearance bridges?
