Transportation MD 24, Sections A And G > Projects > MD 24, Sections A And G KEY CHALLENGES & PROJECT DETAILS MDOT-SHA’s first Construction Management At-Risk project Remediated the slope supporting MD 24 with reinforced soil lifts and live stake along Rock Bank Repaired roadway pavement Improved roadway drainage Instituted a vibration monitoring system to protect a nearby historic iron mill that was under restoration. While a natural imbricated stone wall is viewed by park users and homeowners, it is supported by a concealed caisson/sheet pile/wire wall system providing roadway support that resists the scour forces of the stream. Planted slopes with live stakes and trees for stabilization vs. hardscape elements which maintain the area’s natural rural landscape. Site challenges included a large watershed, complex geotechnical conditions, and stringent environmental concerns focused on the “creeper” freshwater mussel, an endangered species in the US. PROJECT DETAILS: Project Owner: Maryland Dept. of Transportation | State Highway Administration Location: Harford County, MD Status: Completed on time and under budget. Close
