Purpose

  • Improve vehicular, bicyclists and pedestrian safety
  • Improve Levels of Service
  • Increase capacity
  • Improve mobility and accessibility for the public

Need

  • Inadequate capacity
  • Safety for motorists, pedestrians and bicyclists
  • Inefficient mobility and accessibility
  • High accident location
  • High Traffic Volumes
  • Montgomery County priority project

Overview

  • Project Costs
    • Preliminary Engineering – $2.7 M (funded)
    • Construction – $45.8M (unfunded)
    • Right-of-Way Acquisition – $23.8 M (unfunded)

Overview

  • Proposed Grade Separation

    Limits:

    • MD 97 From Mason Street on the south to MD 182 (Layhill Road)

      Approximately 1,900 ft

    • Randolph Road From 300 ft west of Judson Road to 500 ft east of Glenmont Circle

      Approximately 2,200 ft

MD 97 (Georgia Avenue) at Randolph Road

Overview

  • Proposed Grade Separation:
    • Randolph Road lowered over 25 ft
    • ADT:
      • MD 97 – 89,250 (2025)
      • Randolph Road – 52,000 (2020)
    • Structures:
      • (1) Structure carrying MD 97 over Randolph Road
      • (4) Retaining Walls

Overview

  • Major Utility Relocations:
    • PEPCO (Electric) – 69,000 volts
    • Verizon (Communications) – Major Communications and Fiberoptics
  • Complex Maintenance of Traffic Plan:
    • (7) Stages requiring detours to be built to the South to move traffic from the tunnel footprint
  • Typical Sections:
    • MD 97
      • (3) 11'–0" lanes each direction with turning lanes
      • 5'-0" outside shoulder, variable width median, sidewalks
    • Randolph Road
      • (2) 11'–0" lanes each way through tunnel
      • On top eastbound – three lanes – lt, lt/thr, rt
      • On top westbound – four lanes – two lt, lt/thr, rt
      • 8'–0" Shared off street pedestrian/bicycle path
      • Sidewalks

Overview

Typical Section – MD 97 (Georgia Ave) North of Randolph Road

Overview

  • Profiles:
    • MD 97 raised less than 2 ft above existing grade
    • Randolph Rd depressed approximately 25 ft below existing grade
  • Design Status:
    • Plans are approximately 65-70% complete
    • Utility Breakout Project - advance construct PEPCO/Verizon (on-going)
      • (1) Year Design and (2) Year Construction after design is complete
  • Right of Way Plats have been issued
  • Permits required:
    • Stormwater Management, ESC, DNR Roadside Tree Permit

Project Activities and Schedules

  • Location Design Approval – 2002
  • Preliminary Engineering Begins – 2003
  • Milestone Reviews
    • P.I. Review (30%) – January, 2004
    • Semi- Final Review (65%) – November, 2004
    • Right of Way Plats issued – January, 2007
    • ACTT Workshop September 2007

Major Project Challenges

  • Utility Relocations
    • PEPCO and Verizon (Require 2 year Construction)
  • Plan of Action:
    • Relocate utilities from beneath the existing intersection to beneath residential streets
      • Judson Road
      • Sheraton Road

Overview

Major Project Challenges

  • Kensington Volunteer Fire Department (KVFD)
    • Property is a total take
    • Replacement site and funding for new facility under negotiations between:
      • Montgomery County
      • KVFD
    • Prior to taking of the Existing Facility
      • A new site or replacement services at existing locations must be provided prior to condemnation
