The Connaught Tunnel, which carries a rail line underneath Rogers Pass, is about 8080 metres in length; its northeast portal is at an elevation of 3600 feet. The southwestern portal is at approximately 644797 in Figure 5. What is the average slope of the tunnel? Express as an angle in degrees correct to two decimal places. a) Obtain the elevation of SW portal from the map: b) The "rise" is therefore the elevation at the highest point of the tunnel ( feet, or feet) minus the answer from a), which gives m (correct to the nearest integer). c) From the question we know that the "run" is Hence, the average slope is 0 feet. m.
