I-35W Maintenance of Traffic

Hennepin County, MN

Project Overview

I-35W is one of the key arteries feeding into and out of downtown Minneapolis. This project was part of a larger initiative by MnDOT to reconstruct and enhance I-35W from 36th Street to I-94 with diverse objectives including added lanes, pavement and bridge preservation, construction of the Lake Street Transit Station, and improved bicycle and pedestrian access.

Our Work

Isthmus supported the development of the maintenance of traffic (MOT) plan to support this roadway reconstruction project. Our team defined temporary alignments and created preliminary models for all five phases of the construction with subgrade, earthwork quantification, retaining walls, noise walls, ramps, intersections, driveways, and barriers included.

Our team also led the design of the 30+ detour routes on the project. This included local and regional detours to aid the traveling public while certain sections of the project were under reconstruction. The detours included both vehicular and pedestrian routes. Special sign panels were created utilizing SignCAD for guidance to travelers in certain areas where additional destination information was needed due to the detours.
