Kyle Busch will not race in today's Daytona 500 after fracturing his right leg in a violent crash into a concrete retaining wall during Saturday's Xfinity Series race at Daytona International Speedway, a crash that led Speedway President Joie Chitwood III to say the Speedway did not live up to its responsibility today.

Chitwood, who was visibly shaken, said Saturday night that a temporary tire barrier would line the 850-foot stretch of concrete wall for today's 500.

He said steel and foam energy reduction (SAFER) barriers would be added to every possible contact point around the 2.5-mile tri-oval before NASCAR returns in July.

We should have had a SAFER barrier there today; we did not, Chitwood said. We're going to fix that. We're going to fix that right now. We don't want to see any competitors injured here. We have to fix that. We can't allow this to happen again.

Busch, 29, was stabilized by Speedway medics at the crash site, then transported by ambulance to Halifax Health Medical Center for treatment.

Busch sustained a compound fracture of the right lower leg and was in surgery Saturday night, according to a statement from Joe Gibbs Racing team.

He also suffered a midfoot fracture of his left foot in the wreck.

Busch's injuries will sideline him for an undetermined period of time, the release said. Veteran Matt Crafton will serve as the interim driver for Busch's No. 18 Toyota for the Daytona 500. Crafton is a two-time NASCAR Truck Series champion.

Gibbs Racing said an interim driver has not been determined for any Cup races beyond Daytona.

ROGERSVILLE West Greene School Board, at a special meeting Thursday, reviewed the districts options to rebuilding the failed retaining wall at the new elementary center.

The board met with engineers for Michael Baker Jr. Inc. and agreed to move ahead with the construction of a reinforced concrete cantilever toe wall at the site, Superintendent Thelma Szarell said Friday.

Baker was authorized to prepare the engineering design and will complete the bidding process for the walls construction immediately, Szarell said.

The engineers presented several options to the board, all of which would satisfactorily result in construction of a safe, long-lasting retaining wall, she said.

At a building and sites committee meeting earlier this month, the board had reviewed a 700-page report prepared by Baker on the cause of retaining walls collapse. The findings of the report were not released at that time.

The retaining wall, which runs about 760 feet behind the new school and reaches 31 feet at its highest point, collapsed Nov. 6.

The general contractor on the school project, Liokareas Construction Co., filed a lawsuit last week against the district seeking damages for additional work it claims it was required to perform partly in response to issues involving the failed wall.

The company maintains in its suit the design of the wall was faulty. It also claims it had expressed concerns about the walls design on numerous occasions from the beginning of the project.

Retaining walls may look like simple stacked stone, block, or timber. But in fact, they're carefully engineered systems that wage an ongoing battle with gravity. They restrain tons of saturated soil that would otherwise slump and slide away from a foundation or damage the surrounding landscape.

Retaining walls are designed to compliment the landscape as well as providing structural strength and drainage solutions.

Along with sloped landscapes where water runoff causes hillside erosion, ideal locations for a retaining wall include spots downhill from soil fault lines and where the downhill side of a foundation is losing supporting soil or its uphill side is under pressure from sliding soil.

Various soil loads and pressures require different treatment depending on the position of the retaining wall, the load it is designed to take and the use of materials in its construction.

A retaining wall that is required to hold significant soil pressure should be constructed from reinforced concrete or core filled concrete block. In some situations it is advisable for a structural engineer to custom design a solution.

All Day Fencing install concrete block retaining systems and core-filled structural retaining wall systems made from faced concrete blocks. There are six colours currently available, Oatmeal, Bondi Blend, Sunstone, Port Blend, Charcoal and Fossil as shown below.
