Criteria
Alternative
None No changes None None None None None
Reduce all crashes by 48%.
Reduce injury & fatal crashes by
77%.
This alternative places a stop
condition on SR 61 where there is
currently a long stretch of
roadway with free flow
movement from Sunbury to I 71
None None None Temporary (<10
minutes) closure to SR
61 when uncovering
stop signs
$1,152
Based off of the trend of past
signal installations, the number
of crashes does not decrease.
Instead the type of crash shifts
from angle to rear end.
This alternative places a
controlled stop condition on SR 61
where there is currently a long
stretch of roadway with free flow
movement from Sunbury to I 71
None Relocate overhead lines
in northeast corner.
Potential to relocate
underground gas and
telephone lines in
southwest corner
None Flagging operations,
temporary lane
closures, short term
full closure of
intersection to install
spans and signals
$216,000
Reduce all crashes by 71%.
Reduce injury & fatal crashes by
87%.
This alternative provides yield
condition movement for all
roadways at the intersection
Acquisition from 7
property owners
amounting to 1.2 acres
of acquisition.
Relocate power,
telephone, fiber, cable,
and gas, water.
Potential historic
property/structure in
southeast corner. NOI
and BMPs required.
Part width

two of the four roads
to remain open at a
time

Reduce all crashes by 71%.
Reduce injury & fatal crashes by
87%. Improved sight of the
intersection for SR 61 southbound
traffic

$1,764,000

656 and Wilson Rd traffic to better
judge when to move into the
intersection. Improved stopping
sight distance for SR 61
southbound traffic
This alternative provides better
sight distance of SR 61 traffic but
does not change the operation of
the intersection
Acquisition from 3
property owners
amounting to 0.3 acres
of acquisition.
Relocate power,
telephone, fiber, cable,
and water.
None Full closure of SR 61
north of the
intersection. Detour is
1.8 miles longer than
original route
