Speed limit on the Connector to increase from 55 to 60 mph
To improve safety and traffic flow, the speed limit on four miles of the Connector (I-184) will be raised from 55 mph to 60 mph as the recent resurfacing project in that area has concluded, the Idaho Transportation Department announced. The new speed limit will take affect with the changing of the signs, weather permitting, on Tuesday, Oct. 30.
Idaho State Police, local law enforcement agencies, and area city leaders met with the Transportation Department in early June to discuss the change.
The section in question is the segment of the Connector from the Flying Wye to River Street.
The Connector averages about 57,000 vehicles per day.
ITD traffic engineers set the limit at the speed at which 85 percent of the traffic is driving, to determine a safe and reasonable speed for a given road section. This is in accordance with federal safety guidelines, ITD officials sais. According to research, setting a speed limit according to that 85th percentile produces the fewest crashes.
The posted limit is a maximum speed under ideal driving conditions. With wet, icy, or snow-covered roads, foggy weather or congested traffic conditions, it is always prudent to travel slower than the allowed limit, officials said.
"Speed-limit signs cannot replace common sense," said ITD southwest Idaho Traffic Engineer Kevin Sablan. "They are intended to supplement -- not substitute for -- the driver's judgment."
