&quot;Significantly more than $1.7m to build a roundabout&quot;<p>No. Look again. The quoted text says &quot;$1.7 million to design and build the <i>roundabouts</i>&quot;. Plural. That was three roundabouts, not one, on &quot;51st Ave S, Renton Ave S and S Roxbury ST&quot;. And some of the objections you just now raised have been addressed in links I gave earlier, including examples of SDOT proposals for roundabouts in urban Seattle.<p>I give up. You have decided on your answer and no real-world information will change your personal beliefs. You win.
