Plans for new
bridges in the Gateway Blvd. extension to the new Urschel Laboratories were
presented to the Porter County Drainage Board Monday morning.
The maps presented
by Project Manager Mike Bailey of Tonn and Blank, Donald Oliphant of
Christopher Burke Engineering, and Jeff Ban of Development Visions Group,
propose a 21’ wide by 10.5’ high ConTech steel multi-plate radius arch with
an open bottom culvert over Johnson Ditch as the road travels eastward onto
the Urschel development site.

extension of Gateway Blvd. will have four lanes surfaced with asphalt
pavement, according to the plans. Bailey said Lake Erie Land Development
will extend the road from the existing pavement and Urschel will be
responsible as it crosses over Johnson Ditch and Coffee Creek.
Urschel has said it
will pay for the installation of the four lane bridge over Coffee Creek
which will be a 2’ to 3’ concrete box beam. From pier to pier, the bridge
will have two 45’ sections with a 55’ section in between for a total of 145
feet. Guardrails will be placed on each side.
Bailey and Ban said
the two crossings will be built together and construction will be completed
“It’s a pretty
straight forward road extension project,” said Olphant.
arch crossing over Johnson Ditch will be 95 ft. long parallel to the flow of
Johnson Ditch. The structure will have 45 to 90 degree wingwalls designed to
limit the impact of the ditch’s creekbed. Footings will be buried 2 ft. to
limit scour, Olphant said.
He said the
crossing will not adversely affect the floodplain of Johnson Ditch by
following the County’s stormwater design manual and the DNR’s regulations.

the plans on LEL’s behalf, to discharge an outlet into Johnson Ditch.
