Melinda Kaye: More roads just create more traffic jams

We cannot build our way out of congested traffic

As urbanization and infrastructure go hand in hand, it’s natural to assume that constructing more roads and adding lanes to existing roads will accommodate the inevitable increase in traffic that comes with expanding metropolitan areas.

Not so fast. Surprisingly, new roads do not reduce congestion on their own and, in fact, often make it worse in the long run. It turns out that as fast as communities build roads, traffic actually increases and the problem not only remains unaddressed, but becomes even more dire. Simply put, we can’t build our way out of traffic tie-ups because it’s the roads themselves that create them.

Why does this happen? One of the biggest factors is that roads encourage mobility, allowing people to live farther away from where they work, shop and recreate. In a self-perpetuating cycle, retailers and other businesses spring up as the new corridors emerge, further driving up vehicle numbers. We can see this happening right now in Southern Utah as commercial development spreads up and down I-15.

Overall, the United States has spent decades and hundreds of billions of dollars on building and widening roadways — 30,511 new freeway lane miles in the largest 100 urbanized areas between 1993 and 2017, which represents a 42% increase in travel space, while the population in these regions has grown only 32%.

Yet, the traffic congestion persists and worsens.

If more roads are not the answer, what is? No single easy solution exists. However, revamping our transportation budget priorities would provide a start. For example, localities that successfully merge transportation planning with sustainable land use goals should be rewarded with increased funding for doing so. Favoring concentrated urban development and offering viable alternatives to automobile travel are also basic principles that can make a real difference.

Communities must analyze how well their transportation systems connect citizens to their daily destinations and prioritize projects that not only improve these connections but take into account the impact on the natural environment.

It goes without saying that building more roads has an inevitable negative effect not only on our public lands but on our lives. More roads equal more development, elevated carbon emissions, higher levels of noise/light and destruction of wildlife habitat. In the relentless pursuit of more roads, irreplaceable natural resources are destroyed. Opportunities for future generations to experience an unspoiled, natural environment are forever lost.

Here in Southern Utah, we have already started down this “road to nowhere” with the ill-advised push for adding the Northern Corridor Highway through the Red Cliffs National Conservation Area and the similarly short-sighted proposal to build Long Valley Road through Fort Pearce Area of Critical Environmental Concern, public lands specifically designated to protect threatened and endangered species.

We need to think long and hard about sacrificing our precious public lands and open space in the false hope that more roads will solve traffic problems. They won’t.

Superior alternatives have unfortunately been rejected by authorities without a sound reason or with no reason at all. There are alternatives that do not require the extreme environmental encroachments that have become increasingly frequent and that cause our public lands and urban residents to suffer. Common sense demands that we choose a different route.
