King's Highway 402

While recently visiting Ontario I drove the entirety of King's Highway 402 from the Blue Water Bridge to KH 401 near London.


The western terminus of KH 402 is in Sarnia of Lambton County on the St. Clair River at the Blue Water Bridge.  The history of the Blue Water Bridge can be found on the previous blog below.

KH 402 is a limited access freeway which is 102.5 Kilometers (63.7 miles) in length.  The first section of KH 402 was designated in 1953 when a limited access approach road from the Blue Water Bridge to KH 7 and KH 40 was opened.  Although plans had been announced to connect KH 402 to KH 401 near London had been announced by 1957 construction of the extension began in 1972.  KH 402 was fully completed to KH 401 by 1982.

Functionally KH 402 serves as a limited access replacement of KH 7 and KH 22 from Sarnia east to London.  This is very apparent comparing the 1931 and 1955 Province Road Maps to a modern roadway map.

KH 402 eastbound begins beyond the Customs Station at the end of the Blue Water Bridge.  Traffic is almost immediately notified at Exit 1 that KH 401 near London is the primary control city.





Speed limits on freeways in Ontario are signed usually slower than their American counterparts.  KH 402 gradually ascends to a terminal 100 KM/H which equates to about 62 MPH.  At Exit 6 KH 402 meets KH 40.






London is signed as being 107 Kilometers away east of KH 40.  The design difference between Ontario freeways and American Interstates (this is an American highway page after all) east of KH 40.  KH 402 largely lacks inside shoulders and has guard rails surprisingly close to the left travel lane.  This gives the impression when viewed that KH 402 is very narrow.


Exit 15 on KH 402 east accesses County Route 26 on Mandaumin Road. 



East of Exit 15 KH 402 has a truck inspection station.


At KH 402 Exit 25 there is signed access to County Routes 21 and 30 via Oil Heritage Road.



At KH 402 east Exit 402 there is signed access to County Route 8 and KH 21 via Forest Road.



KH 402 crosses over KH 22 east of Exit 34.  KH 22 from Sarnia east to just past Exit 34 runs south of the freeway.  KH 22 remains north of the remainder of KH 402 all the way to London.

At KH 402 east Exit 44 there is signed access to County Route 79 via Nauvoo Road.



East of County Route 79 KH 402 enters Middlesex County.  At Exit 56 KH 402 east accesses County Route 6 on Kerwood Road.



At Exit 65 KH 402 east meets County Route 81 on Centre Road.



At KH 402 east Exit 69 there is signed access to County Route 39 on Hickory Drive.



At KH 402 east Exit 82 there is access to County Route 14 on Glendon Drive.



At KH 402 east Exit 86 there is signed access to County Route 2 on Longwoods Road.



At KH 402 east Exit 98 there is signed access to KH 4 on Colonel Talbot Road.  At Exit 100 there is access to Wonderland Road.



KH 402 east terminates at KH 401 on the outskirts of London.

Mineral King Road, the White Chief Mine, and the unbuilt California State Route 276

Back in July of 2016 I took Mineral King Road east from California State Route 198 to Mineral King Valley within the Sierra Nevada Mountains of Sequoia National Park.  This June I revisited Mineral King Valley and made my way up to the White Chief Mine.


Mineral King Road is a 24.8 mile rural highway maintained by the National Park Service and as Tulare County Mountain Road 375.  Mineral King Road originates at California State Route 198 in Three Rivers near the confluence of the Middle Fork Kaweah River and the East Fork Kaweah River.  Mineral King Road climbs from a starting elevation of 1,400 feet above sea level to 7,830 feet above sea level at the White Chief Mine Trailhead in Mineral King Valley.  Notably Mineral King Road is stated to have 697 curves.


Mineral King Road has an average grade of 5.1% but has several stretches between 15-20% in places.  Pjammycycling has a detailed breakdown on the grade levels over the entirety of Mineral King Road.

Hetch Hetchy Valley; Hetch Hetchy Railroad, abandoned Lake Eleanor Road, and the Wapama Fall Bridge

This June I took a trip out to Yosemite National Park upon receiving my COVID-19 Day Use Reservation.  My destination in Yosemite National Park was out in Hetch Hetchy Valley.  I sought to hike to the Wapama Fall Bridge which took me through some of the path of the former Hetch Hetchy Valley Railroad and abandoned Lake Eleanor Road.



Part 1; Hetch Hetchy Valley, the Hetch Hetchy Railroad, and reservoir roads

Hetch Hetchy is glacially carved valley similar to Yosemite Valley which is located on the Tuolumne River of Tuolumne County.  Hetch Hetchy Valley presently is impounded by the O'Shaughnessy Dam which was completed during 1923 as part of a project to deliver water and hydroelectric power to the City of San Francisco.  Before being impounded Hetch Hetchy Valley had an average depth of approximately 1,800 feet with a maximum depth of approximately 3,000 feet.  Hetch Hetchy Valley is approximately three miles long and as much as a half mile wide.  Hetch Hetchy Valley is located dow…

California's Rogue Sign State Route Shields

While recently revisiting Yosemite National Park I took a couple minutes to capture some of the California Sign State Route shields posted by the National Park Service ("NPS").  None of the NPS shields were actually posted on roadways maintained by Caltrans but were clearly intended to create route continuity with the Sign State Highways.  This phenomenon is not exclusive to Yosemite National Park and can be found on numerous roads not maintained by Caltrans throughout California.



Part 1; Route continuity over who maintains the route

In the very early era of State Highways in California the Division of Highways didn't actually field sign the Auto Trails or even US Routes.  The responsibility of Highway signage fell to the California State Automobile Association ("CSAA") and Automobile Club of Southern California ("ACSC").  The Auto Clubs simply signed Highways on roadways that best served navigational purposes.  These navigational purposes often didn&#…
