Bicycling on Old U.S. 80 in San Diego County

Background | Directions for Eastbound Bicyclists | Directions for Westbound Bicyclists

Background

Bicyclists traveling between San Diego and points east have essentially only one route to follow: Old U.S. Highway 80. Although it has been replaced by Interstate 8, most of the old highway remains and is especially suitable for bicycle travel, especially in rural areas, since Interstate 8 has siphoned off most of the traffic.

The route described here (and the accompanying maps, when available) follows Old U.S. Highway 80 fairly closely, except at the westernmost end, where Highway 80 ended in the middle of downtown San Diego. Because of heavy traffic, most bicyclists prefer to avoid the downtown area whenever possible.

Directions for Eastbound Bicyclists

Numbers indicate approximate distances, in miles, from the beginning of the route.

Map of Bike Route Through Hillcrest

00.00 - Start at Washington Street where Pacific Highway crosses over it. Go east on Washington Street.

Cross the railroad and trolley tracks. The Washington Street Trolley Station is just a short distance to the north on the east side of the tracks.

00.15 - Pass under Interstate 5.

Washington Street and El Cajon Blvd. together form the simplest route east through San Diego. However, the traffic on these streets is fast and heavy, and there is really not much room for bicyclists. I have ridden along these streets, but I don't recommend it. The route described here avoids most of the heavy traffic.

00.73 - Near the top of the first hill, take the University Ave. exit.

00.99 - Cross Goldfinch St. (which is marked as a north-south bike route).

01.51 - Cross Third Ave. (which is marked as a north-south bike route).

Follow University Ave. through the Hillcrest district of San Diego. Although the traffic is heavy through here, it usually doesn't go very fast. It's also a fairly popular bike route, although only the part west of Third St. is marked as such.

The accompanying map shows an alternate route through Hillcrest. You can turn right on Third Ave., left on Robinson St., left on Georgia St. and right on Howard Ave. This route avoids most of the traffic, but it is slightly longer, and it does have some hills. The route described below is almost flat.

There are restricted-turn signs on the ramps leading up to the Georgia St. bridge over University Ave. that make them inconvenient for law-abiding bicyclists.

01.91 - Cross over Highway 163.

02.48 - Turn left onto Park Blvd.

02.87 - Turn right onto Howard Ave., which is a signed bike route.

Map of Bike Route Through North Park and East San Diego

03.02 - Cross Florida St. (which is marked as a north-south bike route).

03.82 - Cross 30th St.

04.21 - Howard Ave. becomes Orange Ave. when it passes over Interstate 805.

05.06 - Cross 40th St. and Interstate 15.

05.56 - Cross Fairmount Ave. (which is a major north-south bike route).

Ascend a very steep hill (about 16%). Fortunately, the hill is only a block and a half long!

06.58 - Cross 52nd St. at the top of the hill.

06.82 - Orange Ave. passes over 54th Street. Just before this bridge, turn right into 54th Street SOUTH.

07.11 - Turn left onto University Ave.

Map of Bike Route Through La Mesa

09.06 - Enter the City of La Mesa near the intersection of 69th Street.

10.88 - Turn right to stay on University Ave. (Left would be Baltimore Dr.)

11.01 - Cross the trolley tracks and Spring St. (The Spring St. Trolley Station is a short distance to the right.)

11.38 - University Ave. merges with La Mesa Blvd. Continue straight ahead on La Mesa Blvd.

12.40 - La Mesa Blvd. becomes Grossmont Center Dr. as it passes under Interstate 8.

12.58 - Turn right onto Murray Dr.

Map of Bike Route Through El Cajon

Pass under Highway 125.

13.83 - Go straight ahead onto El Cajon Blvd. (Murray Dr. turns left.) Pass over the trolley tracks and descend into the City of El Cajon.

14.37 - Pass under Interstate 8 and turn left to stay on eastbound El Cajon Blvd.

15.44 - El Cajon Blvd. veers slightly to the right and becomes Main St. (which is also signed as W. Main St. or E. Main St.).

16.04 - Pass Avocado Ave.

17.30 - Cross Highway 54 business loop. Second Ave. is to the left, Jamacha Rd. is to the right. Go straight ahead.

18.04 - Pass under Interstate 8.

Map of Bike Route Between El Cajon and Alpine

19.55 - Leave the City of El Cajon near Lavala Ln. E. Main St. becomes Highway 80 Business.

20.48 - Cross Los Coches Rd.

22.19 - Turn right on Lake Jennings Park Dr.

Pass under Interstate 8.

22.40 - Turn left onto Olde Hwy 80. (Straight ahead would be Ridge Hill Rd.)

24.20 - Pass under Interstate 8.

26.25 - Turn right onto Alpine Blvd. (Straight ahead would be Chocolate Summit Dr. To left would be Dunbar Lake.)

Pass under Interstate 8.

26.37 - Turn left to stay on Alpine Blvd. (Straight ahead would be Viewside Lane, which is not a through street.)

As you enter Alpine, climb slowly up the first major hill of the route.

An alternate route will take you past the Viejas Casino and Factory Outlet. Turn left at the first overpass and follow Willows Road along the north side of Interstate 8. At the east end of Willows Road, cross Interstate again and enter the Interstate 8 EAST ramp. Although this is the official bike route, it is not favored by bicyclists because the traffic is heavy and the ascent at the east end is significant.

35.20 - When you can go no farther (because the road straight ahead is a rancher's driveway), turn left and then immediately turn right into Interstate 8 EAST. Yes, it is legal to ride on the freeway shoulder here, because there is no reasonable alternative route. This is a fairly significant climb; the grade is as much as six percent, the maximum permitted on most interstate highways.

Map of Bike Route Through Descanso and Pine Valley

38.51 - Exit at Japatul Road.

38.78 - At the end of the ramp, turn left onto Highway 79.

40.10 - Pass through Descanso, where limited services are available.

44.08 - Pass through Guatay, where limited services are available. Start descending into Pine Valley.

45.01 - Pass Pine Creek Trailhead. A 0.45-mile paved road leads to the parking area, where primitive rest rooms are available.

46.58 - Pass Pine Valley Rd. Pine Valley County Park is to the left. Rest rooms and drinking water are available, but the park is open only from 9:30 AM to 5:00 PM. At other times it is locked and inaccessible. Enter downtown Pine Valley, where food, water and lodging are available.

46.96 - Leave downtown Pine Valley and begin a fairly significant climb to Laguna Summit.

48.02 - Turn right at a stop sign onto San Diego County Highway S1, which is still Old Highway 80. (The road to the left is Sunrise Highway.) Cross a cattle guard and Interstate 8, and then continue straight ahead. At slightly over 4000 feet above sea level, this is one of the the high points of the ride. A sign on Interstate 8 marks this as Laguna Summit.

The road from here to the Imperial County line is older and the pavement is rather rough in most places. However, the traffic is light.

48.35 - Cross another cattle guard. Begin a fairly long descent to Buckman Springs Road.

52.18 - Cross Buckman Springs Road at a four-way stop with flashing lights. County Highway S1 goes to the right. To the left, between the eastbound and westbound lanes of Interstate 8, is a rest area with restrooms and drinking water. Continue straight ahead on Old Highway 80.

66.45 - Pass Tierra del Sol Rd. This is the Tecate Divide, 3890 feet above sea level, the other high point of the ride. It's mostly downhill for the next 3.5 miles.

67.34 - Highway 94 joins from the right. Continue straight ahead and enter Boulevard, where food, water and lodging are available. This part of the road is signed as Highway 94.

67.96 - Highway 94 goes off to the left. Go straight ahead on Old Highway 80.

69.87 - Pass McCain Valley Rd.

70.16 - Leave Boulevard.

70.68 - Enter Bankhead Springs. There are no services, because this town has been almost completely abandoned. The road through Bankhead Springs is all uphill.

71.83 - Leave Bankhead Springs. The next 4.5 miles are mostly downhill.

75.21 - Cross a railroad on a bridge built in 1931.

75.46 - Enter Jacumba near mile marker 34.

77.83 - Pass Carrizo Gorge Rd. There are two gas stations about a mile and a half north on Carrizo Gorge Rd. near Interstate 8.

80.68 - Pass near the brake inspection area on I-8. There is a barbed-wire fence between the inspection area and this road. Start descending, and try to control your speed. Some of the pavement ahead is fairly rough.

81.45 - Enter Interstate 8 EAST. Yes, it is legal to ride on the freeway shoulder here, because there is no reasonable alternative route. Prepare for an 11-mile descent into the Imperial Valley, about 2000 feet lower than this point. That's an average grade of 3.4 percent; the steepest parts are about 6 percent.

Map of Bike Route Through Ocotillo

CAUTION: The Imperial Valley gets extremely hot in the summer. Much of the rest of the route passes through rural and desert areas with very few services.

You might want to make a SIDE TRIP to the Desert View Tower. Instead of entering Interstate 8, turn left, go under Interstate 8 and then turn right onto In-Ko-Pah Park Road. Follow it about 1.28 miles, mostly downhill. The tower is open every day from 8:30 AM to 5:00 PM. Admission costs 50 cents. Bottled water and canned soft drinks are available. Return via the same route.

81.60 - Enter Imperial County for the first time. The freeway meanders back and forth across the county line for 2.71 miles before it enters Imperial County for the last time.

84.57 - Pass the Mountain Springs Rd exit. Stay on Interstate 8. There are absolutely no services at this exit. Technically, you are supposed to leave the freeway and re-enter. This is not necessary, but be very, very careful when crossing the exit and entrance ramps. Automobile drivers will not be expecting you to do that!

85.42 - Pass the Runaway Truck Ramp.

91.55 - Pass the California Highway 98 Calexico exit. Be very, very careful when crossing the exit ramp. Automobile drivers will not be expecting you to do that!

93.49 - Turn right onto Imperial County Highway S-80 toward Coyote Wells and Plaster City. This used to be U.S. Highway 80; it is now called Evan Hewes Highway or Evan Hewes Road. The pavement is old and rather rough in most places. If you are riding a road bicycle, you will probably have to slow down a bit. Motor vehicle traffic is fairly light.

97.02 - Cross a bridge and start climbing a small hill. About 0.1 mile to the right, you can see an older Highway 80 which is no longer in use. It runs parallel to this road for 3.75 miles.

From here to Gordon's Well, the pavement is old and rough, but you should be able to maintain a reasonable speed, even on a road bike. Traffic is extremely light because almost all the cars are on Interstate 8, which runs parallel to Evan Hewes Highway and quite close to it. You will be able to see most of signs for eastbound traffic. There are also a few emergency call boxes on the north side of Interstate 8 that you might have to use. There is a barbed-wire fence between Evan Hewes Highway and Interstate 8, but it is full of holes, especially near call boxes.

140.08 - About here, there is a short stretch of especially bumpy pavement.

149.85 - Interchange between Interstate 8 and Highway 98. Continue straight ahead on Evan Hewes Highway.

Map of Bike Route Through Imperial Sand Dunes

157.66 - Turn left into eastbound Interstate 8. Yes, it is legal to ride a bicycle on the freeway here because there is no reasonable alternative route unless you want to hitch a ride on a dune buggy.

Directions for Westbound Bicyclists

The westbound route is more or less the opposite of the eastbound route. The mileages listed here are not as accurate, because mileages were actually measured only in the westbound direction.

0.00 - Ride north on Fourth Ave., cross over the Colorado River into Winterhaven, California.Yuma, Arizona, and pass from the Mountain Time Zone to the Pacific Time Zone. If Daylight Saving Time is not in effect, set your watch one hour BACK (earlier) to Pacific Standard Time.
