N. White Chapel Project Continues with Storm Drainage Improvements

Work on N. White Chapel is progressing and still on track.

Storm drainage infrastructure construction for east and west Chapel Downs continues. Work on the storm drainage improvements under N. White Chapel are set to take place along the southbound lane as soon as the temporary road construction is complete to support shifting traffic off of the existing southbound lane.

Recently, contractors have been working to install the road base to support the temporary road construction along the east side of N. White Chapel. Temporary asphalt will begin to be laid on this road base soon and this will allow us to shift both lanes of traffic east and open up the existing southbound lane for demolition and the installation of the storm drainage improvements in this area. The temporary road construction was designed to allow ample room to maintain the turn lanes and existing lane widths throughout construction so that impacts to traffic can be minimized.

Construction of the retaining and screening walls will continue through the fall.

Construction for the N. White Chapel widening project is estimated to be completed by Spring 2022 for an estimated total cost of $17 million.

New Speed Limit on North White Chapel near Kirkwood Branch Crossing

At the Feb. 5, 2019, City Council meeting, Council had the first reading of a new speed limit ordinance to reduce the speed limit on N. White Chapel Boulevard, from Drum Lane down to Wingate Lane, from 40 miles per hour to 30 mph.

The design consultant for the N. White Chapel bridge repair project analyzed the terrain and the layout of the roadway and recommended to reduce speeds to 30 mph based on engineering standards for roadway design.

Appropriate signs will be placed following this new adoption and prior to reopening the road once construction is complete. This change will be in place for the life of the current bridge.

To date, both headwalls are complete and large rocks known as riprap have been placed up and downstream of the crossing to prevent erosion as a result of inclement weather.

The road will not be reopened until construction is complete.

City Council is set for a second reading of the Ordinance No. 1206 for the reduction, at the next City Council meeting on Feb. 19, 2019.

N. White Chapel Culvert Crossing Bridge Headwalls Taking Shape

Favorable weather conditions over the past few weeks have allowed for the repair efforts of the N. White Chapel culvert crossing to make progress.

Although crews had to make some adjustments that slightly delayed the project, the most recent changes make it easier to see the new crossing take shape. Large rocks, known as rip rap, have been placed around the downstream headwall which will help prevent erosion in future rain events.

In addition to the rip rap, crews have poured the massive concrete footer, or foundation, of the upstream headwall. Weather permitting the headwall concrete will be poured in the coming days.

The road has been closed since late September due to structural damage caused by heavy rains and floodwater.

“I know this road closure has been very inconvenient for the residents in the area, but with the latest progress we are getting closer to having the road open in mid-March,” said Public Works Deputy Director and City Engineer Kyle Hogue. “We really appreciate everyone’s patience as we work to make sure this crossing is safe again.”

Council Approves Engineering Contract for Repairs to N. White Chapel Culvert Crossing

Repairs to the N. White Chapel Culver Crossing are set to begin as early as next week.

Southlake City Council has approved an Engineering Services Agreement with Halff Associates Inc. to provide design services and emergency repair(s) of the N. White Chapel Road Culvert Crossing at Kirkwood Branch Creek. The plan will also include the replacement of the damaged headwalls and pavement.

Due to heavy rainfall and floodwater in late September, the road underwent structural damage and has since remained closed resulting in the area to be declared unsafe for equipment and traffic per the City’s structural consultant.

The City engaged Halff Associates Inc. as a consultant to develop a site-specific engineered plan for repairs, construction plans and specifications for interim improvements.

The City’s goal is to have the roadway re-opened by the end of 2018, weather permitting. In order to expedite the process, Halff Associates Inc. will work with other agencies and provide project coordination services as well as a timeline for a permanent resolution.

N. White Chapel Bridge Repair Design Underway

City staff has engaged a consultant to develop a site-specific, engineered design for the repair of the N. White Chapel culvert crossing at the Kirkwood Branch Creek crossing with the primary focus at this moment to re-open the roadway. The road has been closed since heavy rain and floodwater caused structural damage in late September.

The plan will address replacement of the damaged headwalls and pavement. The goal of the replacement is to re-open the road by the end of 2018, weather permitting. City staff will continue to work with the consultant on a permanent solution to raise the roadway so it will not be subject to future flood events. This will involve a detailed regional drainage study as well as coordination and approval from the U. S. Army Corps of Engineers and other concerned agencies. The City will work with the Corps of Engineers for required permits and seek possible grants to help construct a new bridge. A timeline for the permanent resolution is also being developed.

“Unfortunately this is not something we can fix quickly, but we are working as fast and as smart as we can to re-open the road and be sure it’s safe for the public,” said Deputy Director of Public Works and City Engineer Kyle Hogue. “We know this is frustrating for residents, but I’d like to thank everyone again for their patience and understanding as we work to get the road open again.”
