14  Construction ◦ $10M - $15M  4-lanes only  No Interchange  R/W ◦ $4M  4-lanes  Relocations  Interchange *Currently Unfunded

15  Why to west? ◦ RSA – Critical Crash rate intersections  TH 14/TH 111 in Nicollet  TH 14/TH 99 in Nicollet ◦ Local and Political Momentum  Local Infrastructure planning/needs  Wastewater treatment planning – North Mankato  City expanding  2000 population – 890  2010 population – 1100  23.5% increase
