Lawton officers have chosen a design agency to assist with upgrades and alternative on 5 deteriorating bridges.
Whereas funding to cowl design prices will come from the 2019 Capital Enhancements Program, metropolis officers haven’t recognized the supply to pay for the development work.
The Metropolis Council named H.W. Lochner Inc. to do $618,503 value of design companies centered on alternative of two deteriorating bridges on South eleventh Road over Wolf Creek, simply north of town landfill, and a badly deteriorated residential space bridge on Northeast twenty ninth Road in Coronado Estates; and repairs to eastbound and westbound Cache Street bridges over Wolf Creek, close to Oak Avenue.
“We need to get all of them underneath design,” stated Metropolis Engineer Joseph Painter about plans to fund designs from the 2019 Capital Enhancements Program (CIP).
He stated the hope is to bid the tasks as one development bundle, and having design plans in hand will support metropolis officers as they search funding for development. Mayor Stan Booker stated whereas the CIP can cowl design prices, it doesn’t have adequate cash for development.
The Northeast twenty ninth Road bridge is in such poor form, it already has been closed and can stay so till a brand new bridge is put in, metropolis officers stated.
The 38-year-old bridge passes over a tributary of Wrattan Creek (a part of East Cache Creek) and usually handles 100 autos a day within the residential neighborhood. There have been complaints from some residents within the space about shedding the entry level alongside Northeast twenty ninth Road, however these residents produce other entry factors for getting out and in of the neighborhood, metropolis officers stated.
Troy Travis, Lochner undertaking supervisor, stated the issue with the bridge is beneath, the place pipes that permit water movement are flattening, making the bridge unsafe. The alternative value has been estimated at $610,000.
The extra expensive alternative would be the South eleventh Road bridges close to Pecan Street, estimated at $4.72 million.
Metropolis officers already addressed the problem in April by downgrading what had been a 33-ton weight restrict to 13 tons, an issue as a result of the bridges are positioned on the most important entry highway to town’s landfill on South eleventh Road, that means it’s closely traveled by sanitation vehicles. Painter stated as soon as the bridges are changed, the load restrict may be restored to 33 tons.
Metropolis engineers have stated an evaluation charges the bridges as structurally inadequate and requiring “emergency alternative.” Whereas repairs have been accomplished on the bridges in October 2020 after an inspection coordinated by the Oklahoma Division of Transportation (a bit of metal beam was changed), each have continued to deteriorate, with harm seen on the substructure areas and extreme cracking within the deck, in accordance with Lochner’s evaluation.
Travis stated the principle bridge and overflow bridge are 89 years outdated, with about 3,500 autos a day crossing them.
The Cache Street bridges spanning Wolf Creek are extra closely used — an estimated 7,000 autos a day — and harm there may be repaired, in accordance with Lochner’s evaluation. The 57-year-old bridges have been posted for twenty-four tons, that means fireplace vehicles and freight autos are restricted from utilizing them, Travis stated. Obligatory work contains repairs to growth and development joints, in addition to alternative of bearing assemblies. The bridges additionally can be repainted underneath a undertaking estimated at about $1 million.
