Twin Peaks Rd. just west of I-10
Speed limit on Twin Peaks Rd. is 45 mph at interchange but just as you cross the bridge heading west it suddenly drops to 35 mph and remains at that limit until reaching Silverbell Rd. When the new interchange was just opened the Marana police were operating a speed trap just as you entered the Continental Ranch subdivision but now the speed limit signs have been moved back to the west end of the bridge across the Santa Cruz River. The speed limit on Silverbell Rd which runs north and south through the Continental Ranch subdivision is 45 mph but the speed limit on the new Twin Peaks Rd. is only 35 mph. This lower speed limit seems wrong for safe traffic flow on this new 4 lane boulevard which is similar to Silverbell Rd.
