April 18, 2006: Guidance on I-280 approaching I-74. At a cloverleaf interchange on the south side of the Quad Cities, US 6 leaves I-74, then turns east at the airport, and then intersects US 150. US 150 used to go into Rock Island and end at least within sight of the state of Iowa, but the exact circumstances of its end are unclear. IA 150 was created in the hopes that it would become an extension of US 150, but it runs north-south instead of northwest-southeast line US 150. Now, of course, 150 has been removed completely from far eastern Iowa and ends in Vinton.
