Background:
The current scope of the Project calls for a complete reconstruction of the corridor from NW 58th Boulevard to the I-75 overpass. The Board approved the typical section for the Project on February 17, 2019. The current plan would construct two travel lanes, bike lanes, sidewalks, turn lanes, and a wide median so that future widening, for four travel lanes could be accomplished by widening to the inside without the need to acquire additional right-of-way (ROW) in the future.
The Board approved an agreement with FDOT for capacity enhancements on NW 23rd Avenue on November 12, 2019. This agreement was to provide $1.2 million in matching State funds to the County. These could be used for design and ROW acquisition. Construction funding has not been made available for the Project.
The Project reached the 60% design phase and ROW acquisition has yet to begin but must be completed by 6/30/2024. The cost estimate prepared at 60% plans showed that previously estimated construction and ROW acquisition costs, prepared in 2016, were no longer sufficient. Staff has provided an alternate concept that would construct turn lanes, resurface the roadway, and construct a parallel multi-use path. The Alternate would provide similar features to the Project along the corridor but would cost significantly less than full reconstruction.
