June 14 2004,
the Ohio Department of Transportation will rebuild the
interchanges at I-270/SR 161 and Sunbury Road. This includes
17 bridges, 18 ramps and 5 miles of highway (43 lane miles).
The project will take 3.5 years to complete and will cost
about $126 million.
The new interchanges at I-270
and SR 161 will eliminate weaving, merging and pinch points by
replacing old "cloverleaf" ramps with new
"fly-over" ramps. The new ramps allow motorists to
connect directly with the freeway rather than sharing a lane
with those entering or exiting.
The project will add one to two lanes on
I-270 from just north of SR 161 to about Sunbury Road, and on
SR 161 from I-270 to Little Turtle Way.
A SPUI (Single Point Urban
Interchange) will replace the old interchange at Sunbury Road
and SR 161. A SPUI can pump more traffic through the
intersection while taking the least amount of right of way. Click

is a photo of the SPUI at Sawmill Road and I-270 on Columbus'
northwest side - the SPUI at Sunbury Road and SR 161 will not
look exactly the same).
This is the last of a series of projects
that began in 1993 to accommodate traffic growth and
development on the northeast side. These two projects were
originally scheduled to begin in 2005, but were moved to 2004
to complete work sooner.
