BYPASS PROPOSAL
COMPARISON
This comparative study will address (2) two proposed routes
for the Wilmington area bypass. The (2) routes
will be identified as: ‘5A, C’ ("refined alternative", current ODOT
proposal) and ‘Direct N/S – I-71' (CCCRD proposal and highly popular in the Wilmington
area).
DIRECTIONAL LAYOUT
Both routes begin at the intersection of SR 73 and Airborne
Rd. Both routes continue around behind the Wal
Mart store, cross US 22 / SR 3 (east of Wal Mart), then due north
and cross the railroad (east of the Elk’s golf course).
After crossing the railroad, the (2) routes proceed
differently as follows:
- 5A, C goes basically west along the north edge of
Wilmington.
- Direct N/S – I-71 goes basically north to
I-71.
The (2) routes terminate as follows:
- 5A, C at SR 73, west of Wilmington near Mitchell Rd.
intersection.
- Direct N/S – I-71 at I-71, at or near the existing SR 134 /
I-71 overpass.
TECHNICAL
SPECIFICATIONS
Basic design specification:
- (Both proposals) – 4 lane, ‘super highway’ design with
split-level interchanges and overpasses.
Access to I-71:
- 5A, C – (1) access via US 68
north, 4.1 miles of existing 2-lane highway; (1) access via SR 73 west, 4.3 miles of
existing 2-lane highway.
- Direct N/S – I-71 – direct
access at termination point (interstate type
interchange).
Over-all length (new highway):
- 5A, C – 6.8 miles.
- Direct N/S – I-71 – 6.9 miles
Estimated cost (total):
- 5A, C – per ODOT estimate, $93.1 million.
Note: Does not include estimates for extensive upgrades to
address safety and traffic flow
issues on SR 73 and US 68. Based on the
1994 Miami Valley Regional Planning Commission recommendation for
a Wilmington bypass and the required upgrades to existing Clinton
County highways the TRUE OVERALL COST for bypass and other highway
improvements will total $185.9
million. ODOT does not address the difference of $92.8 million
in their current bypass proposal. That difference along with
other negative environmental impacts are hidden costs related to
ODOT's proposal. ODOT's proposed bypass cannot accomplish
full functionality and provide the over-all community highway
system improvements without the 'hidden cost' upgrades to the
existing highways.
- Direct N/S – I-71 – per CCCRD estimate, $82 to $86 million.
Note: Dollars spent here also
address safety and traffic flow on SR 73, US
68, and US 22 / SR 3. The estimated cost here is the total
cost associated with the proposed route. There are no hidden
costs and the route as proposed would be fully functional and
provide our over-all community the highway system improvements and
benefits as noted.
Truck routing comparison:
For this comparison, (3) three trucks are routed from SR
73 / Airborne Rd. to (3) three different existing locations on I-71
at interchanges with SR 73, US 68, and SR 72. A total of (6)
routes (3 each bypass) were calculated for distance and travel
time. Note: travel times and average
speeds were calculated using identical parameters and methods
for all routes.
- 5A, C: avg. distance = 11.9 mi.;
avg. travel time = 14.46 min.; avg.
speed = 49.5 MPH (4 lane / 2 lane
combination)
- Direct N/S – I-71: avg. distance =
12.3 mi.; avg. travel time = 13.45 min.; average speed = 55.0
MPH (all 4 lane)
COMPARISON SUMMARY
PRO (favorable
advantage):
1.
Does divert traffic on SR 73, US 22 / SR 3, and US 68 around
downtown Wilmington.
1.
Does divert I-71 northbound and southbound traffic to and
from SR 73 / Airborne Rd. and east Wilmington area away from
downtown Wilmington.
2.
Diverts I-71 traffic away from SR 73, US 68, SR 72, and US 22
& SR 3.
3.
Safe, easy, convenient heavy truck I-71 access to DHL and
other east Wilmington area business / industrial
locations.
4.
Less cost.
5.
Overall safety!!!
CON (unfavorable
disadvantage):
1.
Funnels 4-lane bypass
traffic onto existing 2 lane
highways (SR 73 and US 68).
2.
Safety (traffic onto existing 2 lane highways with heavy
traffic and safety problems).
3.
Higher cost.
4.
Tendency to divert SR 73 & US 22 / SR 3 potential
business traffic away from downtown Wilmington business
area.
5.
Overall safety!!!
(Safety issues on SR 73 and US 68)
0. Difficult to
identify any issues – CCCRD is looking for help here
(????????).
Summarize
PRO’s/CON’s to determine over-all
score:
Note: to summarize, each proposal adds it’s PROS
to the other’s CON’s for an over-all comparison score.
RESULTS:
DIRECT N/S – I-71
---- ( 5 + 5 ) -------- 10
5A, C --------------- ( 1 + 0 )
-------------- 1
THAT’S A SERIOUS DEFICIT !!!!
AGAIN, CCCRD NEEDS SOME HELP !!
ARE WE OVERLOOKING SOMETHING
??? TAKE SHOTS AT OUR ANALYSIS
!!!
HELP US OUT !!! LETS US KNOW
WHAT YOU THINK !!!
MAYBE SOMEONE CAN COME UP WITH A DIFFERENT SCORE ???
