Interstate 680 south maintains four through lanes for the continuation onto Interstate 280 north. Three lanes depart otherwise for U.S. 101 north to Santa Clara, Sunnyvale and San Francisco and south to Santa Teresa, Salinas and Los Angeles. Photo taken 11/29/04. |
 |
The interchange between Interstate 680, Interstate 280, and U.S. 101 is a four-level cloverstack, with flyover ramps handling most of the movements. The ramp from southbound Interstate 680 to southbound U.S. 101 is visible here. The confirming shield here is the first one for northbound Interstate 280. Photo taken 11/29/04. |

U.S. 101 advances one mile north to the cloverstack interchange (Exit 384) with Interstate 280 north to Downtown San Jose and Interstate 680 north to Fremont and Walnut Creek. Photo taken 03/25/16. |
 |
Interchange sequence sign posted 0.75 miles ahead of the ramp departure (Exit 384) for I-280 and I-680 north. The forthcoming flyover passes above the cloverleaf interchange with Story Road (Exit 385). Photo taken 03/25/16. |
 |
U.S. 101 north expands to six lanes with an auxiliary lane gained from Tully Road. A two-lane off-ramp (Exit 384) follows for Interstates 280 and 680 north. Photo taken 03/25/16. |
 |
Traffic departs U.S. 101 north for Exit 384 ahead of Story Road. Interstate 280 north arcs southwest toward Downtown San Jose, then north to Daly City and San Francisco.

Prior to reaching Interstate 280 and Interstate 680, U.S. 101 southbound first reaches Exit 386A, California 130/Alum Rock Avenue. California 130 is planned as an potential freeway route between San Jose and the Central Valley, but for now California 130 is a twisty road to Mount Hamilton that does not meet Interstate 5. Photo taken 11/29/04. |
 |
Southbound U.S. 101 reaches Exit 386A, California 130/Alum Rock Avenue. The next exit is Exit 385B, Interstate 280 and Interstate 680. Photo taken 11/29/04. |
 |
Southbound U.S. 101 approaches Exit 385B, Interstate 280 and Interstate 680. Although marked as north, Interstate 280 actually travels west through Silicon Valley briefly before it turns north toward San Francisco. Interstate 680 is signed with Sacramento as its control city, but it passes through several major cities including Pleasanton, Walnut Creek, and Concord along the way. Photo taken 11/29/04. |
 |
The right two lanes of southbound U.S. 101 connect to Interstate 280 north and Interstate 680 north. The left four lanes continue south on U.S. 101, which is signed with a control city of Los Angeles. Photo taken 11/29/04. |
 |
Southbound U.S. 101 reaches Exit 385B, Interstate 280 and Interstate 680. This is one of the rare instances where a three-digit Interstate route with an even first number ends at a non-Interstate. Other examples include Interstate 264 in Virginia Beach, Virginia, and Interstate 635 northwest of Dallas, Texas. Photo taken 11/29/04. |

Westbound King Street approaches Fifth Street, the final traffic signal prior to transitioning onto Interstate 280 southbound. Photo taken 11/26/04. |
 |
The northern terminus of Interstate 280 is in the vicinity of SBC Park, where Major League Baseball's San Francisco Giants play. This sign assembly indicates the transition of the southbound Embarcadero (King Street) onto Interstate 280. Freeway entrances are located just beyond the stoplight, and the viaduct carries traffic to U.S. 101 and beyond. Photo taken 10/16/00. |
 |
The freeway begins without even a trailblazer for Interstate 280, just the freeway entrance shield after the Fifth Street traffic signal. Photos taken 11/26/04. |
 |
 |
Southbound Interstate 280 begins as a viaduct, carrying the freeway high above the neighborhoods of Mission Bay and Potrero Hill. As a result of damage sustained after the Loma Prieta Earthquake of 1989, the Interstate 280 viaduct between Fifth Street and U.S. 101 was reconstructed. Photo taken 10/16/00. |
 |
After traffic from Sixth Street merges onto southbound Interstate 280, the first exit is Exit 56, Mariposa Street and 18th Street in Potrero Hill. Photo taken 11/26/04. |
 |
Southbound Interstate 280, approaches Exit 55, Cesar Chavez (Army) Street. The next exit is the connection to southbound U.S. 101. There is no connection to northbound U.S. 101. Interstate 280 assumes a double decker configuration south of the Cesar Chavez Street interchange until the U.S. 101 transition ramp. Photo taken 11/26/04. |
 |
Now on the top deck of the double decked section of freeway, the left lane becomes exit only for U.S. 101 south to San Jose, while the two right lanes are signed for Interstate 280 south to Daly City and Pacifica. Interstate 280 is also a less congested route to San Jose. Photo taken 11/26/04. |
Perspective from Interstate 280 north |
 |
Northbound Interstate 280 approaches U.S. 101, the Bayshore Freeway. This is the last freeway-to-freeway interchange along northbound. Despite its numbering, Interstate 280 does not connect directly with Interstate 80. To reach Interstate 80 and the Bay Bridge, use U.S. 101 north. Even though the northern terminus of Interstate 280 at 6th Street and King Street is mere blocks from Interstate 80, there is no freeway to freeway connection from Interstate 280 north to Interstate 80. Photo taken 11/26/04. |
 |
Interstate 280 splits with U.S. 101, with U.S. 101 northbound offering the only freeway to freeway connection to Interstate 80. Note the control city of Bay Bridge; it would be helpful if there were also an Interstate 80 shield posted here. Photo taken 11/26/04. |
 |
After the U.S. 101 interchange, northbound Interstate 280 changes into a double-decked, elevated freeway. The northbound lanes form the lower deck, while the southbound lanes follow the top deck of the freeway. Photo taken 11/26/04. |
 |
At the Cesar Chavez Street (former Army Street) off-ramp, Interstate 280 reverts to a traditional elevated freeway. The control city for Interstate 280 is Sixth Street, while some auxiliary signs mention SBC Park, a Major League ballpark located near the northern end of the freeway on King Street. Photo taken 11/26/04. |
 |
The next exit along northbound is Exit 56, Mariposa Street. The towers of the San Francisco-Oakland Bay Bridge, which carries Interstate 80 over the San Francisco, are visible in the distance. From here, the best route to the bridge is via the northbound Sixth Street exit, then turning right onto Bryant Street. This distance is only about four blocks, but it can take a bit of time to make the connection during heavy commuting periods. Photo taken 11/26/04. |
 |
Just prior to the Mariposa Street off-ramp, this sign advises motorists of when there is heavy traffic or delays on King Street (near SBC Park). During those peak periods, traffic is advised to use Sixth Street instead. Photo taken 11/26/04. |
 |
After Exit 56 (Mariposa Street), the next exit is Exit 57, Sixth Street. The two left lanes continue north on Interstate 280 to King Street, while the right lanes exit only to Sixth Street. Photo taken 11/26/04. |
 |
The skyline of downtown San Francisco comes into view as Interstate 280 turns northwest as it approaches Exit 57, Sixth Street. Photo taken 11/26/04. |
 |
On a clear day, the view of northbound Interstate 280 as it approaches downtown one of the most scenic urban freeways. Other stretches of Interstate 280 between San Jose and San Francisco traverse some beautiful rural areas. Photo taken 10/16/00. |
 |
The two left lanes continue along Interstate 280 north to King Street, while the two right lanes connect directly onto Sixth Street north to Interstate 80/Bay Bridge. However, there is no signage anywhere at the north end of Interstate 280 that directs motorists to Interstate 80. Photo taken 11/26/04. |
 |
Northbound Interstate 280 reaches Exit 57, Sixth Street north to Interstate 80/Bay Bridge. The left two lanes will feed directly into King Street near SBC Park, even though King Street is not signed on the overhead signs here. Photo taken 11/26/04. |
 |
After the Sixth Street off-ramp, Interstate 280 prepares to end, as the viaduct descends to ground level. Traffic that continues straight ahead will be dropped onto King Street, which runs parallel to Interstate 80, a few blocks to the north. King Street feeds directly into the Embarcadero, and it turns along the bayshore to connect with Fisherman's Wharf and downtown. Photo taken 11/26/04. |
 |
Northbound Interstate 280 approaches its end as it passes under the flyover ramp to Sixth Street. Photo taken 11/26/04. |
 |
Interstate 280 reaches its northern terminus as the freeway smoothly transitions onto King Street. The first signal ahead is Fifth Street; SBC Park is only two blocks further east on King Street, at the intersection with Third Street. Interstate 280 was retracted a few blocks west of its former northern terminus as a result of earthquake damage and redevelopment in the vicinity of the ballpark. Eastbound King Street transitions directly into the Embarcadero, which offers a direct connection to the many bayside attractions that San Francisco has to offer, including Rincon Point, the Ferry Building, Pier 39, and Fisherman's Wharf. Photo taken 11/26/04. |

Northbound Interstate 280 ends here at the Fifth Street intersection. King Street continues straight ahead from here. There is no end shield present. Photo taken 11/26/04. |
