* [[Washington Park Arboretum#Ghost ramps|Arboretum "ghost ramps"]] (built 1960s), a set of ramps and bridges south of Marsh Island near [[Portage Bay]] in [[Seattle]] that were intended to be an interchange from [[Washington State Route 520]] and the proposed [[R. H. Thomson Expressway]]. When plans for the expressway were scrapped following a citizens' [[freeway revolt]] led by a chapter of the [[Black Panther Party]], the interchange ramps and bridges remained in place and are mostly unused. On January 31, 2013, [[Washington state]] announced that the ghost ramps would be removed sometime between 2014 and 2016.<ref>{{cite news |last=Lindblom |first=Mike |date=January 25, 2013 |work=[[The Seattle Times]] |title=520 "ramps to nowhere" to come down |url=http://seattletimes.com/html/localnews/2020208721_520arboretumxml.html?prmid=obinsite |access-date=January 31, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20140224032627/http://seattletimes.com/html/localnews/2020208721_520arboretumxml.html?prmid=obinsite |archive-date=February 24, 2014 }}</ref> The ramps were demolished in 2017, but a section was left standing in memory of the protests that cancelled the expressway project.<ref>{{cite news |last=Lindblom |first=Mike |date=February 18, 2017 |title=An old Highway 520 crossbeam could be 'urban ruins' honoring anti-freeway activists |page=A1 |url=https://www.seattletimes.com/seattle-news/transportation/an-old-highway-520-crossbeam-could-be-urban-ruins-honoring-anti-freeway-activists/ |work=The Seattle Times |access-date=December 31, 2017 |url-status=live |archive-url=https://web.archive.org/web/20170928202709/https://www.seattletimes.com/seattle-news/transportation/an-old-highway-520-crossbeam-could-be-urban-ruins-honoring-anti-freeway-activists/ |archive-date=September 28, 2017 |df=mdy-all }}</ref><ref>{{cite news |last=Lindblom |first=Mike |date=June 3, 2024 |title=Seattle's famous 'ramps to nowhere' on the way to becoming a park |page=A1 |url=https://www.seattletimes.com/seattle-news/transportation/seattles-famous-ramps-to-nowhere-on-the-way-to-becoming-a-park/ |work=The Seattle Times |access-date=August 30, 2024 }}</ref>
* [[Big Four Bridge]] (built 1895), a {{convert|770|m|ft|adj=on|order=flip}} single-track railroad bridge over the [[Ohio River]] in [[Louisville, Kentucky]], which was abandoned in 1968 and had both its approach spans removed and sold for scrap the following year. In February 2013, the bridge was reopened on one end for pedestrian and bicycle traffic.<ref>{{cite web | url = http://www.bizjournals.com/louisville/news/2013/02/07/big-4-bridge-opens-in-louisville.html | title = Big Four bridge opens in Louisville | author = Staff | date = 7 February 2013 | work = [[Business First of Louisville]] | publisher = [[American City Business Journals]] | access-date = 2014-02-01}}</ref> In May 2014, the [[Jeffersonville, Indiana]], ramp opened, allowing pedestrians and cyclists to travel between downtown Jeffersonville and [[Louisville Waterfront Park|Waterfront Park]] in Louisville.<ref>{{cite web|title=FINALLY: Big Four Bridge opens to Fanfare in Jeffersonville|url=http://www.newsandtribune.com/news/finally-big-four-bridge-opens-to-fanfare-in-jeffersonville/article_6b57953b-0498-52fc-be90-ff9e86ab045d.html|website=News and Tribune|date=20 May 2014 |access-date=10 February 2017}}</ref>
* [[Bridge to Nowhere (San Gabriel Mountains)]] (built 1936), an isolated road bridge over the [[San Gabriel River (California)|San Gabriel River]] in southern [[California]]. The connecting road was never completed. The bridge is a popular destination for hikers.
* A pair of unused overpasses near what is now the southern terminus of [[Connecticut Route 11#Unused bridges, roadbed and ramps|Connecticut State Route 11]].  These bridges were built as part of the original plan for Route 11, which would have seen it extend further south to I-95 in New London.  Construction was halted in 1972 due to lack of funding.
* [[Fort Duquesne Bridge]] (built 1963), a road bridge over the [[Allegheny River]] in [[Pittsburgh]], Pennsylvania, which ended mid-air until the ramps were completed in 1969.
* [[Miles Glacier Bridge]] (built 1910), also known as the "Million Dollar Bridge", was converted from railroad use to motor vehicle use; It is at the northern end of the unfinished [[Copper River Highway]] near [[Cordova, Alaska]]. Construction stopped in 1964 when an earthquake damaged the {{convert|472|m|ft|adj=on|order=flip}} bridge. Although since repaired and reopened, the bridge is nonetheless currently of limited utility due to damage at other points along the route.
* [[Hoan Bridge]] (built 1973), a {{convert|3|km|mi|adj=on|order=flip|0}} road bridge over the [[Milwaukee River]] in [[Milwaukee]], Wisconsin, which was unused until access roads were completed in 1977, was lacking freeway connections at the southern end until 1998, and was "going nowhere again" for two months while closed for major repairs after a span partially collapsed in December 2000.
* [[Mebane's Bridge]] is a road bridge over the [[Dan River (Virginia)|Dan River]] in [[Rockingham County, North Carolina|Rockingham County]] on the outskirts of the town of [[Eden, North Carolina]], which was at the center of the landmark ''Luten Bridge Co. vs. Rockingham County'' lawsuit that made jurisprudence in 1929 when the contractor continued work on it well after the contract to build it was rescinded and subsequently sued to be reimbursed for this work.
* Pier 19 (demolished 2012) of a proposed second span of the [[Ambassador Bridge]] connecting [[Windsor, Ontario]], and [[Detroit]], Michigan. No second span had ever been approved for this privately owned bridge, largely because the proposal would dump excessive traffic onto Windsor city surface streets, but its owners built ramps for the proposed span in an attempt to counter an internationally supported proposal for a [[Detroit River International Crossing]] to the [[Windsor-Essex Parkway]] further downriver.<ref>{{cite news| title=Moroun's 'bridge to nowhere' dismantled| url=https://windsorstar.com/news/Moroun+bridge+nowhere+dismantled/6520868/story.html |author=Dave Battagello| publisher=Windsor Star| date=April 26, 2012}}</ref> The unauthorized ramp was removed in 2012 by court order.<ref>{{cite web| url = http://www.freep.com/article/20120417/BUSINESS06/204170331/| url-status = dead| archive-url = https://web.archive.org/web/20140106033353/http://www.freep.com/article/20120417/BUSINESS06/204170331/| archive-date = 2014-01-06| title = Controversial ramp along Ambassador Bridge being removed {{!}} Detroit Free Press {{!}} freep.com}}</ref>

* The [[San Francisco–Oakland Bay Bridge]] bicycle and pedestrian path was opened in September 2013, but was only connected on the [[Oakland, California|Oakland]] end of the bridge. In October 2016, the connection to [[Yerba Buena Island]] was opened, but {{as of|2018|lc=y}} there is no bicycle or pedestrian access across the western portion of the Bay Bridge to [[San Francisco]].<ref>{{Cite web | url=https://www.baybridgeinfo.org/path |title = BICYCLE AND PEDESTRIAN PATH &#124; Bay Bridge Info|date = 17 March 2021}}</ref>
