Florida’s Pasco County Goes for Wider Roads, Lower CO2

Like so many other places, Dade City / San Antonio, Florida, is experiencing an increase in traffic and needs more capacity. Florida is under more pressure than many states with its large, steady influx of new residents. SR 52 in Pasco County was due for some improvements, including widening and a new alignment. 

Portland-limestone cement (PLC) and supplementary cementitious materials (SCMs) are being used for most of the concrete mix designs for the SR 52 project. PLC can have up to 10% lower CO2 associated with its production while providing similar performance as traditional portland cement. And SCMs like fly ash and slag also significantly reduce the CO2 footprint of mixtures, often while improving fresh or hardened properties of the concrete. It’s estimated that about 500 tons of CO2 will be saved by the PLC alone for this project, not including the reduction provided by SCMs.


FDOT encourages the use of PLC in all their projects for the sustainability benefits and requires that the cement undergo rigorous testing and be approved prior to use. The ready mix concrete supplier provided mix submittals to contractors and convinced them to use PLC for both the sustainable and performance aspects of the material. 


This project will consume 8,700 cu yd of ready mix concrete to:

  • Widen and realign SR 52 from Uradco Place to Fort King Road in eastern Pasco County. Between Uradco Place and Bayou Branch Canal the existing road will be widened to a four-lane divided roadway. 

  • Construct a new four-lane divided SR 52 east of Bayou Branch Canal to create a new alignment and tie into Clinton Avenue. 

  • Widen Clinton Avenue between CR 579 and Fort King Road to a four-lane divided road.


The $81.5 million project is expected to be complete by summer 2024.
