I drive 160 at least 20 times a year more like 40 if you count both ways. Between Mancos and Durango there are several up and down hills that go up and over the LaPlata mtns. the first one being Mancos hill is a decent hill up but not bad then once up you do some up and down but nothing really long or hard. The downhill just west of Durango is not to bad. The worst part is the very beginning of it which must be the 6% part. However after the initial part it drops to less. overall it is not bad at all road is good plenty wide has decent shoulders along much of it
