| Immediately after the California 82 interchange, westbound Interstate 380/Kopp (Portola) Freeway prepares to reach its end at Interstate 280. The merge sign in the distance is the onramp from California 82/El Camino Real, while the guide sign indicates that traffic bound for Pacifica and Daly City should use Interstate 280 northbound. Photo taken by AARoads (11/26/04).

|
| This reassurance shield, located after the onramp from California 82, is the only reassurance shield found along westbound Interstate 380. Given the short duration of the route, perhaps an END shield should have been placed here instead. Photo taken by AARoads (11/26/04).
|
|
| Westbound Interstate 380 approaches its final exit, the junction with Interstate 280/Father Junipero Serra Freeway. The intent is to extend Interstate 380 from Interstate 280 west to California 1, but opposition and environmental concerns stalled the project. At this point, the most likely construction alternative may be to extend 380 as far west as California 35, Skyline Drive. Proposals for this surface from time to time, but no serious plans have emerged. Photo taken by AARoads (11/26/04).

| The two left lanes connect to Interstate 280/Serra Freeway southbound, while the three right lanes connect to Interstate 280/Serra Freeway northbound. Photo taken by AARoads (11/26/04).
|
|
| Westbound Interstate 380/Portola (Kopp) Freeway reaches its western terminus here, at the split between southbound and northbound Interstate 280. Accommodations have been made for the eventual extension of Interstate 380, in case the freeway is ever extended west to California 35 or California 1 in Pacifica. Photo taken by AARoads (11/26/04).

| This mileage sign along southbound Interstate 280 is the first indication of the pending interchange with Interstate 380 east to San Francisco International Airport and U.S. 101. Photo taken by AARoads (11/26/04).
|
|
| Southbound Interstate 280 approaches Exit 43A, Junction Interstate 380 east to U.S. 101 and San Francisco International Airport. Exit 43B, which connects to Sneath Lane and San Bruno Avenue, would have been the western extension of Interstate/California 380 if it had been constructed. Photo taken by AARoads (11/26/04).
|
|
| The next three exits along southbound Interstate 280 are Exit 43B, Sneath Lane and San Bruno Avenue; Exit 43A, Junction Interstate 380 east to U.S. 101 and San Francisco International Airport; and Exit 42, Crystal Springs Road. Photo taken by AARoads (11/26/04).
|
|
| Southbound Interstate 280 reaches Exit 43B, Sneath Lane/San Bruno Avenue and approaches Exit 43A, Junction Interstate 380 eastbound. Note the covered up shield for Sneath Lane/San Bruno Avenue. Photo taken by AARoads (11/26/04).
|
|
| Southbound Interstate 280 reaches Exit 43A, Junction Interstate 380 eastbound to U.S. 101. Interstate 380 is the best route from Interstate 280 to San Francisco International Airport. Photo taken by AARoads (11/26/04).
|
|
| Now on the transition ramp from southbound Interstate 280 to Interstate 380 eastbound, the stub end freeway for Interstate 380 is visible on the second level of the interchange. The transition ramp is the first level, and Interstate 280 forms the third level of the interchange. There is space allocated for an extension of Interstate 380 to the right (west) of the interchange. Photo taken by AARoads (11/26/04).

| The only interchange between Interstate 280 and U.S. 101 along eastbound Interstate 380 is the junction with California 82. Nearly the entire mainline of Interstate 380 can be seen in this one picture. Photo taken by AARoads (11/26/04).
|
| Perspective from Interstate 380 East
|
|---|
| Eastbound Interstate 280 reaches Exit 5, Junction California 82/El Camino Real. This is the first offramp after the Interstate 280 interchange, and it is already time to warn of the pending junction with U.S. 101. Note that the exit numbers used on Interstate 380 envisions an ultimate configuration that begins at California 1 and ends at U.S. 101. Photo taken by AARoads (11/26/04).

|
| The left two lanes continue east on Interstate 380 to connect to North Access Road and South Airport Boulevard. The middle lane transitions onto northbound U.S. 101, while the right lanes exit onto southbound U.S. 101, with a direct connection to San Francisco International Airport. Photo taken by AARoads (11/26/04).
|
|
| Eastbound Interstate 380 reaches Exit 6A, Junction U.S. 101 South to the Airport and San Jose. The next exit is Exit 6B, Junction U.S. 101 North to San Francisco, and the final exit of the freeway is Exit 7, South Airport Boulevard. Interstate 380 directly transitions onto North Access Road, which serves a variety of aviation-oriented businesses that are situated north of the airport property. Photo taken by AARoads (11/26/04).
|
|
| Now on the transition ramp from eastbound Interstate 380 to southbound U.S. 101, the two lane exit immediately splits, with the right lane exiting into the airport entrance lanes, while the left two lanes merge onto southbound U.S. 101. Photo taken by AARoads (11/26/04).

| Upon departing from the parking lots and roadway that connects the terminals at San Francisco International Airport, these signs direct motorists to the freeway system, including U.S. 101, Interstate 280, and Interstate 380. Although the airport is situated about a half-mile south of the U.S. 101/Interstate 380 interchange, there is a direct connection via an elevated ramp between the airport exit and the eastern end of Interstate 380. Photo taken by AARoads (11/29/04).

|
| Interstate 380 offers a quick route between the airport and Interstate 280. This allows traffic bound for the western half of the city of San Francisco as well as travelers bound for Marin County and points north to use California 1/19th Avenue to traverse the city and connect to the Golden Gate Bridge without having to drive through the city on Van Ness Avenue (U.S. 101). In effect, the right two lanes provide connections to areas north of the airport, while the left two lanes connect to southbound U.S. 101 en route to San Jose. Photo taken by AARoads (11/29/04).
|
|
| While the previous two sign bridges were placed by the airport, the next sign bridge is a button copy sign that was Caltrans' standard sign until 1999. The destination for Interstate 380 is San Bruno, but it is also the best route to Pacifica and Daly City, as well as western San Francisco. Photo taken by AARoads (11/29/04).
|
|
| After the two left lanes exit to U.S. 101 southbound, the two right lanes prepare to split between U.S. 101 north and Interstate 380 west to Interstate 280. The ramp for Interstate 380 will parallel the main lanes for U.S. 101 between the airport interchange and the junction with Interstate 380, a distance of about a half mile. Photo taken by AARoads (11/29/04).

| U.S. 101 skirts by San Francisco International Airport as it travels north along the Bayshore Freeway between San Jose and San Francisco. After the main exit to the airport, this mileage sign is the first indication of the pending junction with Interstate 380. The interchange with Interstate 380 is a little more than a mile north of this point; traffic merges onto U.S. 101 from the airport about a half mile north of here. Photo taken by AARoads (11/26/04).
|
|
| As U.S. 101 passes under the tangle of ramps associated with the airport interchange, the Bayshore Freeway approaches Exit 423B, Junction Interstate 380 west to Interstate 280 (one mile). Photo taken by AARoads (11/26/04).
|
|
| After the San Francisco International Airport interchange, northbound U.S. 101 approaches the junction with Interstate 380. Between the onramp from the airport and the interchange with Interstate 380, an elevated ramp to the east (right) of U.S. 101 carries traffic on a two-lane viaduct between the airport and Interstate 380. That ramp is visible in this scene, about one-half mile south of Interstate 380. Photo taken by AARoads (11/29/04).

| The Interstate 380 elevated viaduct is visible from U.S. 101 northbound after the airport interchange. Photo taken by AARoads (11/29/04).
|
|
| Northbound U.S. 101 reaches the offramp for San Bruno Avenue. The next exit is the transition ramp from northbound U.S. 101 to westbound Interstate 380. Photo taken by AARoads (11/26/04).
|
|
| Northbound U.S. 101 reaches Exit 423B, Junction Interstate 380 west to San Bruno and Interstate 280. The same exit options are available on the Interstate 380 viaduct, offering a view of both signs from one vantage point. Photo taken by AARoads (11/29/04).
|
|
| The interchange between U.S. 101 and Interstate 380 is a three-level stack interchange. Flyover connections from northbound U.S. 101 to westbound Interstate 380 and from eastbound Interstate 380 to northbound U.S. 101 form the top level. Photo taken by AARoads (11/29/04).

| Perspective from Airport Boulevard northbound
|
|---|
| Airport Boulevard parallels U.S. 101 between San Bruno Avenue (Exit 423A) and Gateway Boulevard/San Mateo Avenue (Exit 424). As the boulevard leaves airport property and enters the city of South San Francisco, it approaches the eastern end of Interstate 380. Use either the left or right lane on northbound Airport Boulevard to connect to Interstate 380 west to Interstate 280. Photo taken by AARoads (11/26/04).
|
|
| Upon reaching the Interstate 380 overpass, you can turn left to merge onto the Interstate 380 freeway. However, you can also make a right here (on to North Access Road) to make a 270-degree turn onto Interstate 380 westbound, with a connection to U.S. 101. Check out the next photo, which shows the connection to Interstate 380 and U.S. 101 via North Access Road. Photo taken by AARoads (11/26/04).

| After the signalized intersection with Airport Boulevard, eastbound North Access Road approaches the right turn ramp onto Interstate 380 westbound to U.S. 101 and Interstate 280. Photo taken by AARoads (11/26/04).
|
|
| North Access Road turns south to meet this traffic signal, which marks the eastern end of Interstate 380. A right turn connects directly onto the freeway, while a left turn follows North Access Road toward a variety of aviation and weather-oriented businesses. Photo taken by AARoads (11/26/04).

| Westbound Interstate 380 begins its journey after the North Access Road traffic signal, then splits into two ramps: one for U.S. 101 north/south (right lane) and the other for Interstate 380 west to Interstate 280 (left lane). Photo taken by AARoads (11/26/04).

|
| The autumn sun sets over the Interstate 380/U.S. 101 interchange. Westbound Interstate 380 crosses over U.S. 101, with connecting ramps flying over Interstate 380 to make the connection to U.S. 101. Photo taken by AARoads (11/26/04).
|
|
| After the U.S. 101 interchange, Interstate 380 finally begins to look like a standard freeway. Helping to earn its nickname as the "shortest, widest freeway" in the country, Interstate 380 westbound widens out to three through lanes and two auxiliary lanes for the upcoming California 82/El Camino Real interchange. However, Interstate 380 starts to get ready for its western terminus right after the California 82 interchange ... at least until Interstate 380 is extended as planned to meet California 1 south of Pacifica. Photo taken by AARoads (11/26/04).
