Take I-95 from either Baltimore or Washington and Exit 41A (Route 175 East - toward Jessup). Continue on Route 175 East to Route 295, which is the Baltimore/Washington Parkway. St. Lawrence the Martyr Church and Parish Center are located on the Southwest corner of the Interchange of Route 175 and the Parkway. The parking lot is just before the southbound ramp from Route 175 onto the Parkway. Turn right into the Church parking lot, and the Parish Center will be on your right opposite the Church.
