BC Highway 40 Trip

Lillooet to Gold Bridge

Page 1 of 2

Distance from Vancouver to Lillooet: Approximately 250 km, if via Highway 1 West and Highway 99 (Seat-to-Sky) North.

Liked: Fine views of Carpenter Lake, Bridge River Canyon, and Marshall Creek Falls. Access to Gun Creek Recreation Site, many trails and several FSRs.

Of Note: Frequently narrow and winding road with steep unbarricaded drop-offs. Much of the road is gravel. Dust from passing vehicles on gravel surface, especially along Carpenter Lake. Rockfall hazard. Numerous large and small rocks on the road. Avalanche hazard in the winter season. No cell phone signal for most of the road.

BC Highway 40 runs for just over 100 kilometers from the town of Lillooet to a tiny community of Gold Bridge. Along the way, this semi-dangerous, partially unpaved road passes by some very impressive views. Interestingly, this highway does not appear to be officially numbered. Aside from ONE mentioning on a sign in Lillooet (indicated with a red arrow in photo #6), there isn't a single sign along this highway showing its number. The number 40, however, does appear in maps, and many folks in BC do know what "Highway 40" refers to. There are three roads which compose Highway 40: it starts in Lillooet where Moha Road begins off Main Street. Shortly, Moha Road turns into Bridge River Road (also known as Lillooet-Pioneer Road). Finally, at Terzaghi Dam, Carpenter Lake Road along Carpenter Lake takes over as Highway 40 all the way to Gold Bridge.

The main difficulty while driving on Highway 40 is watching the road while checking out all the great views around you. Considering the number of blind corners, the need to dodge numerous small and large rocks littering the highway, and steep unbarricaded drop-offs, it's much safer to pull over for a particularly good view.

Also, Highway 40 does get used by logging trucks and other industrial traffic, so watch out for that too, especially on particularly narrow stretches of the road.

BC Highway 40 starts in the town of Lillooet, and there are two ways to get there from Vancouver: first is Highway 1 East to Lytton via Fraser Valley-Hope-Yale-Boston Bar, then take Highway 12 from Lytton to Lillooet. Or, like we did this time, Highway 1 West to Horseshoe Bay, then Highway 99 (Sea-to-Sky) via Squamish-Whistler-Pemberton to Lillooet. The latter is a more scenic, albeit a more challenging drive, with steep grades past Pemberton. If driving on Highway 97 South towards Cache Creek, turn right onto Highway 99 a few kilometers before Cache Creek, and you'll get to Lillooet that way too.

1-2. Here we are on Highway 99, driving North from Pemberton and approaching an intersection where turning right would shortly lead to the beginning of Highway 12 (to Lytton) and continuation of Highway 99 (to Cache Creek). But, driving straight, would lead to Lillooet and (over 100 kilometers later) Gold Bridge via Highway 40. The red arrow points to a "Welcome to Lillooet" sign. All the mileage in this trip report is based on this sign as a starting point, so zero your odometer at that sign if you want to follow our mileage markers.

3. We went straight at the intersection shown above, and here is a distance info sign (shown with a green arrow in photo #2). Shalalth and Seton Portage can be reached via Highway 40 and Mission Mountain Road - the turnoff is at Terzaghi Dam 51 km later.

4. Just around the corner, another sign indicates that a right turn is required to reach Gold Bridge and Seton Portage. This short stretch between the intersection seen in photos #1 & 2, and Main Street seen straight ahead, is called Seton Lake Road.

5. Now on Main Street in downtown Lillooet. To hike a very fine Red Rock Trail, turn left at 6th Avenue.

Main Street Lillooet BC

6. Highway 40 starts where Moha Road begins off Main Street, 3.3 kilometers from Welcome to Lillooet sign. We are approaching that left turn. Canco gas station (located adjacent to KalTire) serves only 87 grade gasoline, as well as diesel, and it's your last chance to fuel up before Gold Bridge. Note the red arrow in the photo below - it points to the only Highway 40 sign reference that we saw on this trip.

7-8. Turning left from Main Street onto Moha Road. BC Highway 40 begins here. There is a Buy-Low food store immediately to the right after you make that left turn, and it's the last substantial food store on this trip.

16. BC Highway 40 at 18.6 km after the Welcome to Lillooet sign. By this time it is probably already called Bridge River Road / Lillooet-Pioneer Road.

21. At 32.1 km, there is a large pullout on the left side. There is a great Bridge River and canyon view here, as well as Horseshoe Bend Trail which gets down to the river, and which we hiked a few days later.

British Columbia Highway 40

25. At 40.4 km, a big rock is hanging right above the highway, and there are some large cracks there, so avoid stopping under that rock, as it might not stay there for much longer.

27. At 50.9 km, we are approaching Terzaghi Dam and a major intersection, where a left turn would lead to Seton Portage and Shalalth, while going straight (this would now be Carpenter Lake Road) would be the continuation of BC Highway 40, and would lead to Gold Bridge and Bralorne.

28. Here is that intersection, at 51.2 km. Coordinates: N 5047.393' W 12213.486'. Elevation: 643 meters.
