The River Valley Business Park Development Agreement between the City and Opus Development Company, L.L.C. (Developer) includes provisions requiring construction of public improvements consistent with the adopted West End Industrial Site Traffic Impact Study, dated June 28, 2022. The improvements are described as the Plan B Improvements and include: 

• Colburn Drive Extension, which consists of extending Colburn Drive north connecting to Mobile Manner Drive and construction of a permanent cul-de-sac removing the connection to Emery Way/Old Brick Yard Road.
• Intersection improvements (roundabout) at County Highway 69

The intersection improvements at County Highway 69 are not programmed in the City's Capital Improvement Plan and are subject to Scott County approval and development of adjacent properties east of County Highway 69. 

Construction of the Colburn Drive Extension must be completed in 2024 to support the development of and access for the River Valley Business Park subdivision.

Plans have been prepared and are ready to solicit public bids to construct the Colburn Drive Extension improvements. Upon approval, the advertising and bidding will commence with a scheduled bid opening in April 2024. Bids would then be considered and awarded with construction of the improvements scheduled for the summer of 2024.
