The Request for Proposals (RFP) for the design, construction, operations, maintenance, and financing (Design-Build-Operate-Maintain-Finance), in the official procurement jargon, just hit the streets a few days ago. Procurement documents, including all of the technical standards for construction, can be found here: I-69 Section 5.
The Final Environmental Impact Statement (FEIS) and Record of Decision (ROD) for Section 5, which provides all of the background, maps, interchange details, costs, assessed alternatives, etc., can be found here: I-69 Section 5 FEIS and ROD.
In particular, the RFP states that:
the successful Proposer (the “Developer”) shall develop, design, construct, finance, operate, and maintain the I-69 Section 5 project. The I-69 Section 5 project consists of upgrading approximately 21 miles of existing State Route 37, a four-lane median divided highway, between Bloomington, IN and Martinsville, IN to an interstate highway (the “Project”).
The Final Request for Proposals was issued 2013-10-15. Proposals are due 2014-01-21. INDOT anticipates making an award on or round 2014-02-19.
As a reminder, Section 5 goes from State Road 37 in Bloomington, IN and extends north approximately 21 miles to SR 39 in Martinsville, IN:
