Northwest Main – Lino Lakes, MN Traffic Impact Analysis │ June 2025 18 anticipated at the study area. With the full buildout of Scenario 1, Main Street is generally expected to be over the capacity of a two-lane road and would likely need to be expanded to four lanes. Furthermore, the intersection of Main Street & 4th Avenue does not operate acceptably with side street stop control under Design Year (2045) Scenario 1 conditions. A roundabout is likely the best option at this intersection in the long term. SimTraffic and Rodel queueing results were reviewed, and the intersection of Main Street & 4th Avenue sees excessive side street queueing which causes operational issues at the site access points along 4th Avenue. Furthermore, severe queues are anticipated at all roundabouts along Main Street. Additionally, Sunset Avenue is anticipated to experience heavy traffic during the AM peak hour due to the school traffic at this time. The southbound approach at the Sunset Avenue & Lilac Street roundabout is anticipated to operate at LOS D with long 95th percentile queues (54 vehicles). However, the roundabout operates at an overall LOS C and operations along the corridor are not expected to present an issue.
