In May 1967, [[Construction bidding|bidding]] began, after construction had been delayed by that of the I-5 and I-8 freeways, both of which had been given higher priority. This first portion would run from Wabash Boulevard to around Madison Avenue (a distance of {{convert|3.5|mi|km|disp=or|abbr=on}}), and the next portion would include the I-8 interchange.<ref>{{cite news | title=State Asks Bids for Freeway In E.

By March 1970, the original section between Home Avenue and near I-8 was almost finished.

A second border crossing in the San Ysidro area was proposed near the [[Playas de Tijuana]] area, that would be accessible from I-805, although another alternative was considered near [[Brown Field Municipal Airport|Brown Field]].<ref>{{cite news | title=Border Entry Urged Near [[Brown Field Municipal Airport|Brown Field]] | work=The San Diego Union | date=May 15, 1970 |  page=B1|oclc=13155544}}</ref> A formal study on the matter was commissioned in August.<ref>{{cite news | title=City Council Airs New 805 Route | work=The San Diego Union | date=August 26, 1970 | page=B1|oclc=13155544}}</ref> However, this would have added $10&nbsp;million (equivalent to ${{Formatprice|{{Inflation|US-GDP|10000000|1970|r=3}}}} in {{inflation-year|US-GDP}}{{inflation-fn|US-GDP}}) to the cost of the freeway, and possibly delay it by up to 10&nbsp;years; furthermore, most traffic crossing the border was found to head to [[Tijuana]] and not [[Ensenada, Baja California|Ensenada]].<ref>{{cite news | title=$10 Million Loss Seen in 805 Rerouting | work=The San Diego Union | date=September 1, 1970 | page=B1|oclc=13155544}}</ref> Following this, the city of Chula Vista asked that the state proceed with the original plans to construct the freeway, even though it would pass through a San Ysidro neighborhood.<ref>{{cite news | title=Chula Vista Urges Early Road Work | work=The San Diego Union | date=September 10, 1970 | page=B1|oclc=13155544}}</ref>

===Recognition, artwork, and architecture===
[[Image:Miramar op 805.jpg|thumb|left|The La Jolla Village Drive overpass on I-805 northbound, with the Eastgate Mall bridge in the background]]
The Mission Valley Viaduct was recognized by the [[American Society of Civil Engineers]] (ASCE) as the "Outstanding Civil Engineering Project for 1973 in the San Diego Area"; it was designed to match the close by [[Mission San Diego de Alcalá]] with its columns that look similar to cathedral windows,<ref name="spectrum" /> and arch-like shapes etched into the textured concrete. The viaduct was designed to span {{convert|3900|ft|m|abbr=on}}, and use squared-off support columns instead of traditional cylindrical supports. Octagonal columns were to be used on the ramps and the ends of the bridge.<ref>{{cite news | title=Bids Due Soon for Viaduct in Mission Valley | work=The San Diego Union | date=August 11, 1968 | author=Smith, Cliff | page=B1|oclc=13155544}}</ref> Over 600&nbsp;tons ({{convert|600|ST|t|abbr=off|disp=out}}) of steel bars were to be used,<ref>{{cite news | title=Viaduct Takes Shape | work=The San Diego Union | date=August 7, 1969 | page=A28|oclc=13155544}}</ref> and the bridge was constructed as high as {{convert|98|ft|m|abbr=on}} above I-8.<ref>{{cite news | title=Interstate 805 Span Shows Geometric Beauty | work=The San Diego Union | date=August 24, 1970 | page=A3|oclc=13155544}}</ref> The Adams Avenue Bridge over I-805 was also recognized for its {{convert|439|ft|m|adj=on}} span and two tapered supports on the ends of the bridge; in 1968, a [[Princeton University]] engineering professor asked for a copy of the design from Caltrans for educational purposes.<ref name="spectrum">{{cite news | title=Bridges Span Design Spectrum | work=The San Diego Union | date=January 11, 1976 | page=F6|oclc=13155544}}</ref> The construction supervisor, in fact, compared the construction of this bridge to building a boat, and it was constructed from the middle outward rather than the conventional method of building from the ends inward.

Awards for the Eastgate Mall (or Old Miramar Bridge) came from the [[Federal Highway Administration]], San Diego Highway Development Association, and Prestressed Concrete Institute Awards Program; at the time, it was one of the first arch bridges in the state, and did not use traditional concrete pillars.<ref name="spectrum" /> The ''San Diego Union'' (predecessor to the ''Union-Tribune'') published a few freelance articles in 1984 about I-805, complimenting the four-level interchange with I-8 and the [[arch bridge]] at Eastgate Mall, while mentioning that subsequent inflation after their completion would have made such structures more difficult to build if they had been constructed later. Other artwork and architecture that was mentioned included the Wateridge development in Sorrento Valley, and the "Stargazer" building by Alexander Liberman that was lit with fluorescent colors at night.<ref>{{cite news | title=Outdoor Artworks Bring New Beauty to Freeway Travel | work=The San Diego Union | date=August 16, 1984 | author=Lewinson, David | page=E8|oclc=13155544}}</ref><ref>{{cite news | title=Architecture at Its Best in S.D Freeways | work=The San Diego Union | date=February 26, 1984 | author=Jones, Bob | page=F1|oclc=13155544}}</ref>

However, not all forms of artwork along the highway were uncontroversial. In 1977, there were several complaints regarding new billboards that were installed at the northern terminus of the highway, since they blocked the view of the coast.<ref>{{cite news | title=Ruling Awaited on New Billboards On Interstate 805 | work=The San Diego Union | date=January 30, 1977 | author=Ball, Neil | page=B16|oclc=13155544}}</ref> In 1981, an illegal mural that was determined to be incomplete was discovered at the I-8 interchange; while Caltrans discouraged the painting of such murals, they were impressed with the portion that had already been completed.<ref>{{cite news | title=I-805 Graffiti Artist Sought | work=The San Diego Union | date=April 2, 1981 | author=Gross, Greg | page=B1|oclc=13155544}}</ref> Art Cole, the artist, stepped forward to the department, and was allowed to finish the mural of a desert highland sunrise; following this, Caltrans made efforts to have other murals commissioned.<ref>{{cite news | title=Mural Is Given to San Diego | work=The San Diego Union | date=August 28, 1981 | page=B13|oclc=13155544}}</ref>

===Expansion===
[[File:Interstate 5 and Interstate 805 Sorrento Valley interchange.jpg|thumb|"Dual freeway" at northern I-805 terminus]]
The construction of a "dual freeway" at the northern end of I-805 was discussed as early as 1989, referring to the two [[carriageways]] needed for each direction of the freeway, resulting in four total. It would require drivers to use the new local lanes to access eastbound SR&nbsp;56 from I-5 or I-805. The project would allow for trucks to use the new lanes to assist in merging with traffic. However, it faced opposition from local residents, concerned about the loss of the view from their homes, as well as environmentalists concerned about nearby wetlands.<ref>{{cite news | title=Bottleneck at I-5/805 Is Dilemma | work=The San Diego Union | date=April 30, 1989 | author=Weisberg, Lori | page=B1|oclc=13155544}}</ref> Further objections espoused the view that the congestion would continue to increase, regardless of what was done, and that the new road would be at capacity in a few years.<ref>{{cite news | title=Residents Express Anguish at Plans to Expand I-5 Junction | work=Evening Tribune | date=June 2, 1989 | author=Kubik, Agnes | location=San Diego | page=B8|oclc=37687666}}</ref> The San Diego Association of Governments (SANDAG) funded the construction with $110&nbsp;million (equivalent to ${{Formatprice|{{Inflation|US-GDP|110000000|2000|r=3}}}} in {{inflation-year|US-GDP}}{{inflation-fn|US-GDP}}) in mid-2000.<ref>{{cite news | title=Highways Receive Bulk of Money in SANDAG Transportation Plan | work=San Diego Union-Tribune | date=July 22, 2000 | author=Arner, Mark | page=B3|oclc=25257675}}</ref>

Construction of the "dual freeway" began in early 2002, at a cost of $182&nbsp;million<ref>{{cite news | title=I-5/805 Merge Widening Under Way | work=San Diego Union-Tribune | date=March 1, 2002 | last=LaRue | first=Steve | page=B2| oclc=25257675}}</ref> (equivalent to ${{Formatprice|{{Inflation|US-GDP|182000000|2002|r=3}}}} in {{inflation-year|US-GDP}}{{inflation-fn|US-GDP}}).

The intention is to allow the vehicles to travel at shorter following distances and thereby allow more vehicles to use the lanes. The vehicles will still have drivers since they need to enter and exit the special lanes. The system was designed by Swoop Technology, based in San Diego County.<ref name="RoboBus">{{cite magazine | url=https://www.wired.com/cars/futuretransport/magazine/15-08/st_robot | title=Robot Buses Pull In to San Diego's Fastest Lane | magazine=Wired | date=July 24, 2007 | access-date=August 19, 2007|archive-url=https://web.archive.org/web/20121110112944/http://www.wired.com/cars/futuretransport/magazine/15-08/st_robot|archive-date=November 10, 2012 |oclc=24479723}}</ref>
