Island Route 420 (cancelled)

Island Route 420 (IR-420) was a planned island route that was meant to connect Midtown to the Lower Northeast Area, through Island Route 20. Although S.I.T.A funding was ready, and officials from Los Renos, Ozarksas, and Virnavia had approved the route, it was struck down by the city government of Roseville, with the officials stating: "In accordance with Roseville city laws, which supersede some Seaward government laws in the case of environmental aid, no roadways may be built within city limits. We cannot allow IR-420 to be built in city limits and will prevent any attempt to doing so, out of concern for our local environment."

IR-420 was originally designed as a ramp extending down into Roseville, where drivers could go north towards Los Renos and Ozarksas and south towards Virnavia. After it's first rejection, the Lower Northeast committee (which included Roseville officials), S.I.T.A, and the Metro Seaward Transit committee designed another routing plan that every subregion accepted. Instead of an IR-420, IR-220 was designed as a southeastern split at Cresent beach, which went down and connected to the E-W Connector, not entering, but just outside of Roseville's city limits. Another spur, IR-120 was built splitting off IR-20 at the Railport Loop Rd in North Seaward, that went directly into Ozarksas and Los Renos. This plan, although costing more, and adding a slower connection from Midtown to the Lower Northeast, was approved by all committees.
