The existing roadway consists of two 12'-0" traffic lanes, an 8'-0"interior shoulder, and a 10'-0"exterior shoulder for an overall out-to-out width of 42'-0". It is anticipated the proposed structure will be widened to accommodate three 12'-0"traffic lanes with 12'-0"shoulders. However, the proposed structure design will be determined during the design portion of the Progressive Design-Build contract. The following structures are included in this project: S.N. 101-0133: I-39 over the Kishwaukee River S.N. 101-0134: I-39 over the Kishwaukee River Construction oversight services are required for construction inspection, supervision, documentation of pay quantities and related forms for record keeping, Construction & Materials Management System (CMMS) documentation, verification of construction layout including GPS work for layout and documentation, As-Built survey, submittal of pay estimates, change orders, on-site quality assurance material testing, off-site PCC and HMA testing, and night-time inspection as needed.
