Overall Findings

• Majority of Hot Spots located at intersections and in incorporated areas (Tiffin & Fremont).

• Majority of signals are incandescent bulbs (LED is preferred).

• Several deficient vertical curves located in Wyandot and Seneca Counties.

• All horizontal curves meet current design standards.

• Several Areas have Utility Poles and Ditches within clear zone.

Stakeholder Concerns

• Concerns of the stakeholders include:

–Congestion caused by seasonal traffic

–Lack of safe passing areas on SR 53

–Increase in crashes that may coincide with seasonal increase in traffic

Passing Lanes

• Lack of comfortable passing areas can cause drivers to become trapped behind slower moving vehicles for long distances on SR 53.

• Minimal safe passing areas could be a safety issue.

– not reflected in the crash data for SR 53.

• Lack of passing lanes is more of a driver satisfaction or congestion issue.

• DLZ estimates the addition of a passing lane at approximately $1,120,000 per lane mile.

Super 2

Changes the typical cross section of the road to:

• One 12 foot travel lane in each direction

• Paved shoulders, 10 feet wide

• Passing lanes spaced every 8 to 10 miles.

• Left turn lanes at major intersections if not already present.

Super 2

• Construction cost and rate of return was broken down into 4 segments:

– Upper Sandusky to Tiffin (SR 18); approximately 19 miles

– Tiffin (Northern Corporation limit) to SR 12; approximately 11 miles

– SR 12 to the US 6/US20 Bypass; approximately 5 miles

– Turnpike to SR 2; approximately 11 miles

Super 2Estimated Cost:

• Upper Sandusky to Tiffin (SR 18)

$35,246,200

• Tiffin (Northern Corp. Limit) to SR 12

$18,410,034

• SR 12 to US 20

$9,223,066

• Turnpike to SR 2

$17,187,800

Rate of Return

• Upper Sandusky to Tiffin (SR 18)

-10.27%

• Tiffin (Northern Corp. Limit) to SR 12

-11.60%

• SR 12 to US 20

-5.14%

• Turnpike to SR 2

-10.68%

Break Time

Definitions• Cost Estimate:

– Construction cost only

– 15% inflation & 30-50% contingency

– R/W Cost is land only (No structures/relocations)

• Rate of Return

– Can be positive or negative

– Function of construction cost

– Relevant crash reductions factors (CRF’s)
