State Routes 315/750 Intersection Improvement Project

Introductions Project Team Public Meeting

WHY ARE WE HERE TODAY

• Add turn lanes on State Route 315 and SR 750.
• Stabilize the slope with vegetation at worst spot.

Second Project

• More slope stabilization along SR 315

What Changed

• In 2012, ODOT secured funding
• Turn lanes on SR 750 always part of the proposal
• Turn lanes on SR 315 new

PROJECT HISTORY

Purpose Improve Safety

• Decrease congestion at SR 315/750
• Stabilize the slope
• ODOT presented initial alternatives to

the public in 2008.

• Alternative selected in 2010.

THE CURRENT PROPOSAL

• Left turn lanes on SR 750 eastbound and westbound
• Left turn lanes on SR 315 northbound and

southbound

• Retaining wall on the west slope of SR 315 in both

directions

• SR 315 realigned slightly west of its current position

THE CURRENT PROPOSAL

Turn Lanes and Slope Stabilization

First Project

• Construct a wall along the road
• Next to River
• No impacts to the Olentangy River

PROPOSED SCHEDULE & TRAFFIC IMPACTS

• Construction in phases
• SR 315 and 750 will not be closed simultaneously
• Prior notification of closures/restrictions/posted

detours will be provided

• Signage will be used
• Could begin August 2013
• 4- month project

HOW DO WE BUILD THAT WALL?

• Drill Holes
• Install Steel Beams into bedrock
• Fill in with Concrete
• Preserve as much Vegetation as possible

EXAMPLE

SR 78 Morgan County River closer to road You can’t see the beams Not all vegetation removed

RETAINING WALLS AT INTERSECTION

This is similar to what will be installed along the slope of SR 315 west of the road near the intersection.

SR 315

Original Hillside

ENVIRONMENTAL IMPACTS SR 315

• Some right of way required west side for turn lanes
• Five existing culverts replaced under road
• Culverts carry water from five streams
• Old Mill called “Mulzer Mill”
• National Register of Historic Places
• Ruins impacted
• Some vegetation and trees removed for turn lanes

ENVIRONMENTAL IMPACTS SR 750

• Some right of way needed from both sides of the road north

and south of SR 750.

• One culvert will be extended all the way to the river.
• Some trees and vegetation will be removed to

accommodate turn lanes.

Section 106 of the Historic Preservation Act

Because of the potential impacts to the Historic Mulzer Mill, ODOT is bound by Provisions identified in 36 CFR Section 800.16(y) which defines an “undertaking” as a project, activity, or program funded in whole or in part under direct

• r Indirect jurisdiction of a federal agency (in this

case the Federal Highway Administration).
