Editing Interstate 980 (section)

==Route description==
Although I-980 physically goes north and south, it is signed as an east&ndash;west route like SR&nbsp;24. Immediately after traffic leaves I-880 on elevated connector ramps, I-980 then descends below grade to pass under downtown city streets. The freeway then ascends above grade to pass over [[California State Route 123|SR&nbsp;123]] (San Pablo Avenue) and 27th Street before reaching I-580 and SR&nbsp;24.{{citation needed|date=February 2024}}

The freeway itself lacks overhead guide signs mentioning I-980. Immediately after exit&nbsp;1B (SR&nbsp;123/17th Street) going eastbound on I-980 is a guide sign mentioning the junction with I-580. Likewise, the guide signs on westbound I-980 at exit&nbsp;1D (18th Street) list I-880 and [[San Jose, California|San Jose]] as a [[control city]]. Since 2018, Jackson Street and I-880 south have been signed as exits&nbsp;1B and 1A in the westbound direction.{{citation needed|date=February 2024}}
