Take the Ohio Turnpike towards Cleveland.
Get off the Ohio Turnpike at the I-90 exit.
Follow I-90 to downtown Cleveland, then just after crossing the bridge (near Jacobs Field) take the exit for East 9th. Loop around to the right on the exit and you’ll be going north on East 9th. Turn right at the first light, which is Carnegie.
Stay on Carnegie past 55th St, through the Cleveland Clinic, then eventuall past/under the RTA (rapid transit) station and up a hill.
Now the directions split depending on where you are going…
If you are going straight to case campus and the Astronomy Department:
Turn left at Murray Hill Rd — it’s the stoplight halfway up the hill, just past the RTA station. At the next stoplight, curve left (the road becomes Adelbert), and you will pass the parking structure on your left. Don’t enter the structure here, though (that’s the “permit only” entrance); instead, keep going and then turn left at the next stop sign. Then take an immediate left into the feeder area to the parking garage where there is visitor parking.
If you are going to Notre Maison
At the stoplight at the top of the hill, bear right (not the sharp right turn, just bear right onto Cedar Ave). Get in the right lane.
At a stoplight a few streets up, turn right onto Grandview.
At the end of Grandview, go through a double stopsign and turn left on North Park. Pass a school and fenced field on left and begin to pass houses on the left. The FOURTH house on the left is Notre Maison, marked by the Low BLACK IRON FENCE across the front of the property. Park in oval driveway.
