the county does have a detour - in the NB direction in twn. of Lloyd (just outside village of Highland) the hwy. dept. detour and detour for the ACR NB would be to turn RIGHT on So. Chodike Rd. then LEFT onto SR 299 CAUTION! high speed traffic no TCL - follow SR 299 to OLD New Paltz Rd. the existing route NB
in the SB direction after the left onto SR 299 CAUTION! no TCL here INSTEAD of turning right onto CR 12 New Paltz Rd. as per the ACR would CONTINUE on SR 299 to So. Chodike Rd. - I think this is the official hwy. dept detour HOWEVER... cyclists in the SB direction could CONTINUE on the existing route CR12 then turn LEFT onto CR 15 Riverside Rd. off CR12 New Paltz Rd. - after CR 15 New Paltz Rd. is closed NOTE: the Hudson Valley RT is ALSO CLOSED - follow this road to SR 299 then RIGHT onto SR 299 then RIGHT onto So. Chodike Rd. (should be about 1/2 mile from last turn) then LEFT onto CR 12 New Paltz Rd.
the above MAY be the hwy. dept. detour from the North IE: New Palttz - in the NB direction would be better to ride SR 299 to Old New Paltz Rd. (old 299) - ONE left turn without a TCL on this busy hwy. would be more than enough - to follow the above SB route in reverse would require a SECOND LEFT turn across the hwy.
I had read on the Hud Val RT site newsletter that the expected completion of the work will be in July? - but I don't think so figure on untill Labor Day weekend to be sure
