In 1968, Chapter 282 swapped a portion of the route with Route 96:
“Route 96 near the confluence of the Shasta and Klamath Rivers
southwesterly to Route 5 near Klamath River Bridge
the north city limits of Yreka.”
Klamath River Bridge (02-SIS-263, PM 56.7/57.2)
In July 2016, it was reported that a historic but deteriorating 85 year old bridge crossing the
Klamath River on Route 263 is proposed for demolition and replacement in
the near future, according to Caltrans documents. A Caltrans historic
bridge survey determined that the Klamath River Bridge meets criteria to
be listed in the National Register of Historic Places. As such, Caltrans
must do some form of mitigation, but it could be as little as an
informational plaque. The northernmost of a set of five bridges built in
the 1930s on former US 99 through the Shasta River canyon, this piece of
road was at that time “the most thickly bridged section” of
any state highway in California. An alternate plan to blast tunnels
through the rock formations was rejected. The bridge has an unusual 600
foot radius curve built into it, negating what would be sharp right angle
turns on the north side. It is of “T-beam” construction, a
less common variety of girder design associated with the 1930s. The
original “window railings” were replaced with solid barriers
in the late 1970s. The new bridge’s design and exact location is yet
to be revealed but its construction is set to take out an old residence on
the north bank of the river, the former Kamp Klamath (later called
Richie’s Store and Gas Station) that served early day motorists.

In January 2017, the CTC approved for future consideration of funding a project in Siskiyou County that will replace the Klamath River Bridge on Route 263 near the city of Yreka (near the intersection of Route 96, making the scope 02-SIS-96, PM 103.00/103.6, 02-SIS-263, PM 56.7/57.2). The project is programmed in the 2016 State Highway Operation and Protection Program. The total programmed amount is $22,940,000 for capital and support. Construction is estimated to begin in Fiscal Year 2018-19. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2016 State Highway Operation and Protection Program.
In August 2018, it was reported that the CTC approved
$18.6 million for a project that will replace the Klamath River Bridge on
Route 263 from north of the Shasta River Bridge to Route 96 near the city
of Yreka, and Route 96 east of State Route 263 in Siskiyou County.

In December 2018, the CTC approved the California Department of Transportation’s (Department) request for an additional $4,600,000 for the State Highway Operation Protection Program (SHOPP) Bridge Replacement project (PPNO 3424) on Route 263 and Route 96 in Siskiyou County, to award the construction contract. This is an increase of 30% over the construction capital amount. This project is located at the intersection of Route 263 and Route 96 near the city of Yreka, in Siskiyou County. The project will replace the existing Klamath River Bridge, which is over 85 years old and has deteriorated extensively. The new bridge will be wider than the existing bridge to accommodate wider shoulders to meet current standards. The contract award status is pending approval of this request for supplemental funds. Construction would begin in Spring of 2019, would take 350 working days, and be completed in November 2021.
The Engineer's Estimate (EE) for this project was
updated in May 2018 which included consideration of the project’s
remote location. In addition, the Department requested an increase to the
original programmed amount, to account for both the higher bidding
environment and higher construction costs throughout the region. The
Department discussed the bid results and compared bid prices with the
contractors, including those who opted out of the bidding process.
Although 15 contractors, sub-contractors and material suppliers obtained
contract plans for the project, only two contractors submitted bids for
this project. The contractors stated that this project includes many
difficult, specialty contract items which only a few contractors can
perform. Some of the difficult items on this contract include constructing
the bridge foundation in a rocky, river environment and support falsework
for an arch structure over a flowing river. The difficulty to construct
this bridge, the bridge’s remote location and environmental
constraints due to the proximity of the Klamath River, present added
challenges and higher risks to the contractor. All these challenges and
risks resulted in a limited number of bidders and higher contract bids.
The EE was developed appropriate for the project including the challenging
location of the existing bridge. However, the EE was still undervalued as
the current trends were beyond expectations. While there are only two
bidders on the project, the existing bridge is in an extensively
deteriorated condition, and urgently needs to be replaced to ensure the
safety of the traveling public. The Department has reviewed the bid
results for possible mathematical or material unbalancing in accordance
with 23CFR 635.102, and 23CFR 635.114. The bids appear to be
mathematically balanced and there is no evidence of material unbalancing
of the low bid.
