Knowing about the current construction projects might help in planning your Yellowstone visit. There are four of them currently listed for the park. Be aware that the first one I will name includes totally closing the road between 10 pm and 8 am, so you will have to find an alternate route—but night driving defeats most people’s purpose of seeing the sights, anyway.
1. Madison to Norris junctions: The new bridge is open to traffic as of July 12th, but there will still be construction and delays on the road along the Gibbon River.
2. The South Entrance to Lewis Falls is being resurfaced. This project will probably be completed by August.
3. Sylvan Pass has a one-mile stretch which will see construction work. No dates announced for this one.
4. The Canyon to Fishing Bridge junctions segment through Hayden Valley, where so many bison usually congregate in the summer, will have construction delays (in addition to the bison jams) starting on July 26th.
