A Missouri transportation official says it will likely cost about $3 million to replace the highway overpass that partially collapsed when rail cars smashed into one of its support pillars after a cargo train collision.

Seven people in two cars on the Highway M overpass in Scott County were injured, none seriously, when two 40-foot sections of the overpass crumpled early Saturday.

The collapse occurred after a Union Pacific train hit the side of a Burlington Northern Santa Fe train at a rail intersection. Derailed rail cars then struck columns supporting the overpass, causing the collapse.

Mark Shelton, engineer for the Missouri Department of Transportation, said Sunday that the bridge replacement is estimated to cost about $3 million, and the bridge is expected to reopen in early September.

Authorities have identified a man killed by a train in western Iowa as a Kansas man.

Harrison County Sheriff Patrick Sears says Friday that 59-year-old Alan Nelson of Lawrence, Kansas died Monday after being struck by a Union Pacific train just east of the Missouri River.

Sears says the death has been ruled a suicide.

Kansas City officials have approved a five-year renewal contract for red-light cameras at several intersections around the city.

The city approved the first contract with American Traffic Solutions five years ago, and the city council voted Thursday to approve the five-year extension. Police have said red-light running and crashes are down at most of those intersections where the red-light cameras have been installed. The contract was set to expire June 30th.

Nearly 191,000 red-light tickets have been issued since the program began in Kansas City, although the number has declined in the past two years as drivers have become more aware of the cameras. Citations dropped nearly 24 percent between 2010 and 2012.

Seven people were injured when two cargo trains collided on tracks under a Missouri highway overpass, causing the overpass to partially collapse.

Scott County Sheriff’s Dispatcher Clay Slipis said the collision happened around 2:30 a.m. Saturday near Chaffee when a Union Pacific train hit a Burlington Northern train.

Slipis said several cars derailed and hit a pillar of the Highway M overpass, bringing it down. Two cars were on that stretch of road.

Seven people — five in the vehicles and both train conductors — were taken to a hospital. Slipis said all but one was treated and released; the seventh is in good condition.

The National Transportation Safety Board says it’s sent a crew to investigate the cause.

A Missouri woman has been killed in an explosion on a barge on Beaver Lake in Arkansas.

The Benton County coroner says Kayla Woolsey, 23, of Hollister, Missouri died Friday.

Officials say she was thrown from the barge she was standing on in the Lost Bridge area of the lake near Garfield, Arkansas.

Sheriff’s Deputy Kesha Guyll told reporters that another person was welding on the boat at the time of the blast shortly after 1 p.m. Friday. Guyll said investigators believe a spark from the welding ignited fumes — but that it wasn’t immediately known what type of fumes.

Two people have died in a helicopter crash in southwest Missouri.

The Federal Aviation Administration says the helicopter crashed late Friday night in southwest Missouri after taking off from the Lucas Oil Speedway in Wheatland.

FAA regional spokeswoman Elizabeth Isham Cory says both people on board died in the crash. She says the wreckage was found early Saturday.

The identities of the victims have not been released.

The helicopter was registered to Lucas Oil, which declined comment Saturday.

A busy state highway between Lawrence and Kansas City could be widened to six lanes, paid for with so-called “high-occupancy toll lanes.”

A new study be regional transportation officials suggests mass transit and carpooling would be free along Kansas Highway 10, but single-occupant vehicles would have to pay a toll.

The Five County Regional Transportation Study suggests that K-10 between Lawrence and Johnson County become a partial toll road.

KDoT says Thursday the highway should be widened in the next 20 years to six lanes.

The report identifies projects for future years, after the current state roads program ends in 2020.

A tractor-trailer truck driver has pleaded not guilty to charges stemming from a crash that killed two other motorists in southwest Missouri.

Lei Sun, 31, of Alhambra, California entered the pleas through an interpreter Friday to two counts of involuntary manslaughter. He remains held in the Greene County Jail, with his next court appearance scheduled for late July.

Sun is accused of speeding on U.S. 60 near Republic and failing to stop for a line of traffic on March 27th. His rig rear-ended a car and a pickup truck, pushing them into another truck.

The collisions killed pickup driver Lawrence Coan Junior of Kimberling City, and the driver of the car, Corey Gresham of Macon, Missouri.

Sun’s public defender has called the crash a tragic accident.

Kansas legislative negotiators have agreed on a proposal for cutting income taxes further and setting the state sales tax at 6 percent.

The deal emerged Friday from talks among three senators and three House members to reconcile differences between the two chambers.

House Republicans drafted the plan, and GOP senators accepted it to see whether other lawmakers would support it. The House would vote on it first, possibly Tuesday.

Republican Gov. Sam Brownback wants to follow up on massive income tax cuts enacted last year without creating budget shortfalls. He proposed canceling a sales tax decrease scheduled by law for July.

The 6.3 percent tax is set to drop to 5.7 percent. GOP senators wanted to keep the tax at its current rate, but House Republicans resisted.

Both chambers adjourned until Tuesday, guaranteeing that the legislative session will go into its 95th day.

Governor Sam Brownback says Kansas residents want their legislators to get tax policy right and are willing to accept the annual session going longer than anticipated.

The Republican governor said in a statement Friday that it’s challenging for lawmakers to enact policies for improving the economy while balancing the state budget.

Brownback said of Kansans, “They’re interested in solutions, even if it takes some overtime.”

His statement came two days after he admonished lawmakers that it was time for them to wrap up their session.
