I-39/90 Corridor Expansion, Madison to Illinois Line

CORRE provided construction oversight and inspection services for these highly complex Mega Projects on the I-39/90 corridor from 2017 – 2021. The projects expanded the northbound and southbound lanes of I-39/90 from two lanes to three in both directions.  The projects utilized crossovers to maintain two lanes of traffic in both directions during construction.  Reduced speed limits, temporary raised reflectors, gawk screen, glare screen, and temporary barrier wall with access gates were used to enhance safety. These projects had Federal Oversight and reconstructed/expanded a total of 11-miles of interstate and the CTH N interchange.

Items of work included major grading and rock excavation, concrete and HMA pavement, 12 bridge replacements, five staged box culverts, four concrete panel retaining walls, 14 overhead signs, ITS, street lighting, storm sewer, sidewalk, pavement markings, and a new weigh-in-motion system which included device installations and static scale for the southbound WisDOT Safety & Weight Enforcement Facility. In addition, living snow fence, shrubs, and trees were planted providing improved aesthetics for the corridor.

The 11 miles of interstate reconstruction consisted of four separate projects:

• I-39/90, CTH N IC and Area, 2017-2018 ($24M)
• I-39/90, NB Expansion, Church Rd to CTH AB, 2018 ($29M)
• I-39/90, SB Expansion, CTH AB to Church Rd, 2019-2021 ($41M) **2020 Excellence in Concrete Pavement – Gold Award, ACPA National**
• I-39/90, SB & NB Expansion, CTH AB to Belt Line IC, ($31M) 2020-2021
