The Hwy 143 climb starts near Parowan in the fairly remote southwestern section of Utah, sandwiched between 2 other Top 100 U.S. Climbs (#73 Hwy 153 37 miles north and #71 Kolob Terrace Rd 68 miles to the sourth). The first 6 1/2 miles of this climb are a good warm up at 4.8% while the next 4.5 miles ramp up with an 8.4% average grade (10.2% average grade for the steepest part of the climb - 1.7 miles from mile 9.4 to 11.1). Our view is primarily of forest as we climb 11 miles up to the tiny ski resort community of Brian Head. The 3 miles through and beyond Brian Headare more open and less wooded as we are beginning to move close to above tree line.
Roadway-Traffic Report: Very good roadway, but it is a highway, so we do encounter light but fast traveling traffic with minimal to no shoulder to ride on.
