Trunk roads are brighter than freeways

[1ec5]

I find it jarring that trunk roads are brighter – and thus more prominent – than freeways:

This might’ve happened because print maps often stroke U.S. Routes in bright red, but they also don’t tend to make any surface street as wide as this style does. The freeway color seems to be inspired by AAA and other publishers that apply the same tint of red to both U.S. Routes and freeways. The only distinction between these two road classifications is the black casing, to which some other map publishers add a black line down the median.
