From the Longmont Diagonal (CO 119): From the Diagonal, take the Foothills Parkway (keep going straight on Diagonal, DO NOT exit) south to Arapahoe. Take a right (west) on Arapahoe to the next stoplight at Marine Street (the street sign on the right will indicate 38th Street), where you will turn left. Follow Marine until just before the stop sign where it dead-ends at 30th Street. Make a U-turn and park by the meters in front of 3100 Marine Street. You do not need to put money in the meters: your tester will give you a parking permit or pay your meter when you arrive. Proceed into the building, turn left and go to your tester's room (click here for a list of tester room numbers).
