FDOT PROPOSES WIDENING I-10 FROM ALABAMA TO US 29 AND REDESIGNING PINE FOREST AND 9 MILE AS “DIVERGING DIAMOND INTERCHANGES”

Andrew McKay 01/23/20

FDOT will have a meeting on February 4 at Pine Fores UMC to discuss the possibility of widening I-10 to six lanes from the Alabama border to US 29.  However, an additional elemment of their proposal is to radically redesign both the Pine Forest and 9 Mile interchanges as “diverging diamonds.”  This is a relatively new traffic management design FDOT has been trying elsewhere in the state that reduces conflict points by making the non-interstate drivers cross to the opposite side of the road between the two ends of the interchange.  Under ordinary design, there are 12 traffic flow conflict points requiring traffic light control, but the diverging diamond reduces this number to 8, thus reducing the amount of traffic flow interruptions.  However, the design will feel very odd to people unfamiliar with it.  (See drawings)

FDOT release:

Chipley–The Florida Department of Transportation (FDOT) is holding a public meeting regarding the Interstate 10 (I-10) from east of the Alabama State line to west of U.S. 29 Project Development and Environment (PD&E) Study in Escambia County Tuesday, Feb. 4 from 5:30 p.m. to 6:30 p.m. at the Pine Forest United Methodist Church, 2800 Wilde Lake Boulevard, Pensacola.

This meeting is being held to provide interested persons an opportunity to express their views concerning the study. The intent of this study is to widen I-10 from four to six lanes from east of the Alabama State line to west of U.S. 29 and reconstruct the interchanges at Nine Mile and Pine Forest roads as diverging diamond interchanges. This project is being developed concurrently with a separate study for the Beulah Road (County Road 99) interchange PD&E Study.

Maps, drawings and other information will be on display at the meeting. FDOT Representatives will be available to discuss the proposed improvements, answer questions, and receive comments.
