Diverging Diamond Interchange Proposal at I-95 and Hogan Rd
On December 8, 2015, MaineDOT officials provided a presentation to City staff and officials regarding proposed improvements to the Hogan Road / Exit 187 intersection. Crash statistics show a high number of crashes at this location over the past 3 years, with more than a third of crashes causing injuries. Exit 187 is Maine's busiest diamond interchange with 12.7 million vehicles traveling through the intersection annually. In addition, a lack of sidewalks and shoulders on the Hogan Road bridge contribute to serious pedestrian safety issues. In order to alleviate these problems, MaineDOT proposes a diverging diamond interchange solution. In summary, a diverging diamond interchange improves safety by reducing the number of conflict points and will include a dedicated pedestrian and bicycle path in the bridge median.
