At the top of Alexander just before Cliff Shadows the speed limit drops to 25mph the school zone signs also reflects the speedlimit of 25mph, many people become confused and think that the speed limit is still 35mph, the speed limit between Alexander and Durango to Alexander and Cliff Shadows drops from 45 to 35 to 25! If you are going UP alexander toward Cliff Shadow you have to make a right at the light by the park to continue up alexander this section is 35mph, once you see the 25mph silver sign drop your speed, soon after you will see a school zone sigh with the same 25mph posting, this is where the speed limit drops to 25 all the way up. Just before Cliff Shadows on the left hand side right after the bridge before the stop sign there are 1-3 bike cops with radar lidar guns. Be ADVISED!
