Sherman Minton Bridge program aspects development phases, lane closures | In-depth

LOUISVILLE, Ky. (WDRB) – After yrs of arranging, building could start as early as April on a significant renovation of the Sherman Minton Bridge and repairs to nearby roadways on both of those sides of the Ohio River.

The get the job done would be substantially performed by August 2023 and finished in early 2024, in accordance to the proposal by Kokosing Building Co., the contractor Indiana officers chose to oversee the $137 million venture.

Kokosing’s options drop new light-weight on the makeover to the Interstate 64 corridor between Louisville and New Albany, Ind., which Kentucky and Indiana transportation officers hope will insert 3 a long time to the 58-yr-previous, double-decked bridge.

In unique, Kokosing has laid out how targeted visitors would be impacted throughout 5 design segments, such as preliminary options for lane limitations. The all round program assumes that Indiana lets Kokosing and its staff start get the job done by February 9 the Indiana Finance Authority expects to finalize a agreement with Kokosing in late February or early March.  

Even if it is modified, the timetable place forth by Kokosing is a information to how construction will proceed:

Period 1 (April 2021-January 2022) Throughout this stage, crews would rebuild eastbound sections of I-64 in Kentucky and Indiana, like the Sherman Minton. Other perform involves portray the bridge’s truss and “upgrading” the I-265 interchanges with I-64 and I-65 in southern Indiana. Two lanes of the base deck of the bridge would be shut, while a person lane of I-64 East would keep on being open up. Two westbound lanes and an eastbound lane would be open up on the deck higher than.

Stage 2 (January 2022-July 2022) Painting would go on on the bridge, and other eastbound segments would be rebuilt. The closures on the decrease deck would shift, but there would nevertheless be a single eastbound lane open up below. The targeted traffic configuration on the upper deck would not improve.

Section 3 (July 2022-December 2022) Get the job done would transfer to I-64 West, with the reconstruction of the bridge deck and other elevated sections. Crews also would rebuild portions of Spring, Elm and 5th streets in New Albany and begin changing the interstate bridge’s hanger cables, or vertical rods that support the roadway.

Kokosing claims it will use an “innovative” solution – putting in the new cables although the existing types are in place — to speed up construction and make potential cable inspections less complicated. New gusset plates that join bridge associates can be added “the energy is only briefly minimized by just one bolt all through the system,” the company’s proposal states.

All through this section, two lanes of website traffic on the higher bridge would be shut. One particular westbound lane would be open, as would an additional westbound lane and two eastbound lanes underneath.

Section 4 (December 2022-May well 2023) Function would keep on on I-64 West, such as bridge portray and rebuilding of the westbound constructions. Crews would replace the relaxation of the bridge’s hanger cables. Traffic designs would shift slightly on the upper bridge, with two lanes even now closed.

Period 5 (Could 2023-August 2023) As the task nears completion, visitors would return to regular. The bridge painting – a silver shade from the original 1960s-period span – would complete.  

Proposed Sherman Minton Bridge construction phases

Aside from the lane reductions through building, Kokosing will be able to close the bridge fully for 9 straight times and up to a few weekends per 12 months beneath a site visitors prepare authorized by the Indiana Department of Transportation traffic prepare.

That situation would signify a total closure through 54 times of an anticipated 843 full times of get the job done, or just above 6 per cent of the time.

Even before the COVID-19 pandemic, enterprises and residents were involved about how these closures could have an affect on them. In 2019, the One particular Southern Indiana chamber of commerce arrived out in opposition to a whole shutdown.

But in contrast to the abrupt, emergency closure of the bridge in 2011, corporations really should have sufficient recognize during the forthcoming work to discover other routes in the course of individuals whole shutdowns, mentioned Wendy Dant Chesser, the chamber’s president and CEO.

“I really do not believe that everybody’s fired up about it,” she stated. “But I would say that there’s at least an comprehending that they’re not as helpless as they have been the past time. They can program for this.”

Kokosing, of Westerville, Ohio, will perform with Dallas-dependent Jacobs Engineering Team Inc., a designer of the Abraham Lincoln and Lewis and Clark bridges in the course of the Ohio River Bridges Venture.

Kentucky and Indiana are sharing the costs of the task, which as recently as 2020 was predicted to be all around $90 million. But the Kokosing bid recognized last month by the Indiana Finance Authority was a 52 per cent increase in the total cost tag.

Andrea Brady, a task spokeswoman, said the enhance is a consequence of various elements, including a “low-impact targeted traffic approach” and extra repairs prepared to structural steel and the bridge’s concrete substructure, which contains abutments and piers. The new charge was inside 2 percent of a closing engineering estimate, she reported.

Kokosing redacted the expense breakdown in its proposal. Below Indiana public documents law, the organization views these figures as a proprietary trade top secret and doesn’t have to disclose them even right after a closing variety is built, explained Andy Seiwert, common counsel for the Indiana Finance Authority.
