3 Reasons to Turn These One-Way Streets into Two-Ways

Some of Eugene's most prevalent streets through town are sets of one-way pairs-- 11th and 13th, 6th and 7th, Oak and Pearl.  Willamette was one way for a long time, and still has a block or two that only allows south-bound travel.  Strong Towns provides some case-studies as to how two-way streets can create a vast improvement.

Two-way streets offer more exposure for local businesses because cars driving in both directions pass by their storefronts. Two-way streets also slow the cars, meaning drivers and passengers have more time to notice local businesses out the window. Two-ways also encourage more foot traffic because they feel safer for pedestrians.
