I-95 and Oslo Road Interchange Design Project
The proposed project includes the construction of an interchange at I-95 and Oslo Road in southern Indian River County. Oslo Road currently crosses over, but does not provide access to, I-95 at this location. The proposed interchange would be located approximately 5.5 miles north of the existing Indrio Road/SR 614 interchange and 3.8 miles south of the existing SR 60 interchange at milepost. The project limits are defined as, along I-95: ½ mile north and south of Oslo Road, along Oslo Road: ½ mile west and east of I-95 and along 82nd Avenue: 1 mile north of Oslo Road.
The New Interchange project is designed as a rural diamond interchange with partial clover leaf loop ramps at I-95 and Oslo Road. The project also includes the widening of Oslo Road from a two lane facility to a four lane divided facility and the replacement of the existing Oslo Road bridge over I-95. Due to the proximity of the interchange the existing 82nd Avenue will be relocated and 86th Avenue SW connection to Oslo road will be eliminated. The project will include a new construction of 13th Street SW which connects 86th Avenue SW with 90th Avenue SW.
Other project improvements Include:
• An open drainage system that is interconnected by piping to stormwater treatment facilities to collect, convey, treat, and attenuate stormwater runoff. The proposed treatment facility consists of dry retention pond(s).
• Signing and Pavement marking.
• Lighting the interchange ramps, replacing the impacted lighting on I-95 due to the widening, and providing underdeck bridge lighting.
• Intelligent Transportation Systems (ITS) which involves the relocation and/or replacement of the buried fiber optic cable that Indian River County uses as their signal interconnect for their transportation management system.
• Landscaping is also proposed for the interchange to be installed under a separate project sometime after the construction is complete. The proposed landscaping includes the planting of trees along the ramps and the borders of the infield areas and terrace walls on the embankment fill slopes approaching the twin bridges over I-95.
