Development and Analysis of Alternatives

• Initial analysis of all intersection options assumed MD 214 would remain two-lane road
• Two-lane road could not accommodate 2040 traffic from MD 468 to River Road
• 3 corridor options evaluated from MD 468 to River Road
• 4-lanes section (2 in each direction)
• 3-lane reversible (2 lanes WB AM / 2 lanes EB PM)
• 3-lane section (1 lane WB, 2 lanes EB)
• Recommended corridor alternative:
• 4 lanes from MD 468 to Loch Haven Road
• 2 EB lanes and 1 WB lane from Loch Haven Road to River Road

Development and Analysis of Alternatives

• Each roadway alternative includes:
• Bikes lane in each direction on MD 214 from MD 468 to Mayo Road
• Bikes lane in each direction on Shoreham Beach Road from MD 214 to

Triton Beach Road

• Shared-use path along north side of MD 214 from MD 468 to Shoreham

Beach Road

• Shared-use path along south side of Shoreham Beach Road from MD

214 to Triton Beach Road
