The Challenges of Building a Direct Road Between Anchorage and Vancouver

People often wonder why there isn't a direct road between Anchorage in Alaska and Vancouver in British Columbia, following the coasts of southeast Alaska and British Columbia. This article delves into the reasons why such a route is currently unfeasible, including the geology, cost, and history of the areas involved.

Why Not a Direct Road?

The idea of a direct road spanning the coasts from Anchorage to Vancouver might seem plausible, especially considering the existing highways that serve as close to a coastal route as geographically feasible. However, several critical factors make such a vision unattainable.

Geographical Barriers

The rugged terrain, particularly the highly mountainous and fjord-filled regions of southeast Alaska and British Columbia, presents significant challenges for constructing a highway. For instance, the Desolation Sound, a long, winding fjord, as documented in Captain George Vancouver's exploration diary, highlights the difficulty in navigating these coastal regions. Each fjord Captain Vancouver encountered was a dead end, and the quest for the Northwest Passage failed due to the numerous obstacles.

Cost and Practicality

The cost of building a road through such terrain is prohibitively high. Building over such terrain would require extensive cutting and filling, tunneling through mountains, and creating bridges over fjords. The terrain is full of steep mountains, treacherous valleys, and glaciers, making construction highly complex and expensive. Additionally, the sparsely populated nature of the regions means that the economic viability of such a road would be questionable.

Comparisons with Similar Regions

By looking at other regions like Norway and Iceland, which also have fjords but manage to build roads, we can draw a parallel. In these countries, roads often go through mountains and fjords and are supported by dedicated funding mechanisms. For instance, Norway's government is built on a sovereign wealth fund that supports ambitious infrastructure projects. However, for Alaska and British Columbia, with their vast empty landscapes, such support is less likely to be available.

The Alaskan Highway

The Alaskan Highway, although not built along the coast, serves as a counterpoint. This highway was built inland, away from the coast, due to practical considerations during the Second World War. It demonstrates that in certain circumstances, it is often more feasible to take a more inland route to avoid the numerous challenges of coastal construction.

The Whittier Tunnel

The Whittier Tunnel in Alaska is another example of how regions with similar challenges address them. Built to connect Anchorage with Whittier, a port city, the tunnel is a testament to the extensive engineering required to overcome geographical obstacles. However, for a more extensive network like a direct road from Anchorage to Vancouver, the scale and cost would be significantly higher.

Conclusion

In conclusion, while the tantalizing vision of a direct road between Anchorage and Vancouver exists, the reality is that the rugged terrain, high cost, and practical difficulties make such a route unfeasible. The existing highways that follow the coast as closely as possible are the closest we can get with the current practical constraints. As technology and funding continue to evolve, perhaps one day we might find a way to overcome these challenges.
