The route is in good shape. There's some construction on Park Street/US 89 near the Livingston I-90 interchange, but a side path takes us right around it. The only other construction I encountered was some shoulder work on the Battle Ridge Pass descent, but that didn't impact the traveled way.
The weather was cool and breezy. I got sprinkled on in the lower Bridger Canyon and again just outside of Livingston. Northeast winds gave me a tailwind for much of the route. The forecasts for next weekend show it will be much warmer, breezes out of the west (which may hurt a little on the final climbs), and some possible thunderstorms in the afternoon (which is pretty common this time of year). All in all-it should be a great day to be out on the bike.
Here's photos I snapped along the way:
Not unique to Montana, but more common here than most. The cows will go around you-just be calm-then dodge cow pies for the next several miles.A view of the Yellowstone River from Old Clyde Park Road
