The Bonnie Brae Phase 4 Project consists of a four-lane divided roadway, including a 10’ shared use trail, 5’
sidewalk, drainage system and utility replacement. The original scope of the project was from IH-35-Scripture,
it has since been divided into two phases: Phase 4A (Roundabout at Scripture) and 4B (IH-35 - Southern end
of Roundabout). Phase 4A was bid out in spring of 2019 and awarded to DDM Construction. Phase 4A
completed construction in the summer of 2020. Phase 4B is at 90% design and is awaiting approval of this
amendment to be completed.
Amendment #4 includes Level A subsurface utility exploration for design; traffic signal design for signals at
IH-35 service road, Oak Street, and Hickory Street; right-of-way appraisals; landscape design and irrigation
design; environmental services for three (3) parcels required for right-of-way acquisition; and franchise utility
coordination. Bid phase and construction phase engineering services are also included due to the project being
split into separate phases.
