Can't speak for 86, but yes 88 is under reconstruction, but it's not a "Do not travel road". We went from Bingo to Sidney and didn't have any problems w/ the 1 lane. Yea it stunk w/ just 1 lane of travel, but that's the price for progress. Where in the 'daks are you heading OP? Can jump on 81 in Syracuse/Bingo and go up to Watertown and p/u roads to Lake Placid. Take 90 to Utica and then Rte 12 up to Rte 28 to Old Forge and points north thru the 'daks. OR take 90 to 87 (Northway) in Albany to Lake George. Some would say if going to LG to jump off in Amsterdam and run "skinny" road up to 87. Yes you could, but it comes w/ lots of curves, stop/go, city traffic etc. Better off just staying on 90 to 87.
