The red star indicates Sherman, NY, and the two major roads used to get to most attractions are 430 (main street through Sherman) and Interstate 86, which you probably used to get there in the first place. 430 curves around the far side of the lake, and 394 is the route following the west side of the Lake.
From Sherman to the Chautaqua Bridge (I-86) is about 15 minutes.
