Staff Report

Excessive rainfall and flooding have pushed back the projected completion date for a new bridge over Gravois Creek on Green Park Road, City Administrator/City Clerk Zella Pope told the Green Park Board of Aldermen last week.

Work on the new bridge and the redevelopment of a roughly 6,000-foot stretch of Green Park Road from Tesson Ferry Road to Lin Valle Drive began this spring.

Concrete Strategies, the contractor for the bridge project, “has struggled for weeks with excessive rainfall and flooding of the job site,” Pope told the board, reading a June 19 email from Mark Payken of Payken Consulting.

Payken initially was hired by the city to perform right-of-way acquisition for the project. His role since has expanded to include project management and the responsibilities a director of public works or city engineer normally would handle.

While officials originally had estimated work on the bridge would be substantially complete by June, Payken now projects the bridge will be completed and open to traffic by Sept. 1, Pope said at the June 20 Board of Aldermen meeting.

The previous week, Concrete Strategies had completed the “floor” of the box culvert, according to Payken’s email.

“They are currently working to construct the ‘walls’ of the box culvert. Once the ‘walls’ are complete and have sufficient cure time, the ‘roof’ off the box culvert will be constructed,” Payken wrote.

L. Krupp Construction Inc., the contractor for the road project, “continues to make progress installing storm sewers on Green Park Road,” Payken wrote, noting the storm sewer installation would continue for the next two to three weeks. Depending on how the work progresses and the weather, Payken anticipated Krupp will begin full road closures by the following stages:

• 1. Lin Valle to just east of Kohrs.

• 2. Just east of Kohrs to just east of Mueller.

• 3. Just east of Mueller to Tesson Ferry.

“During each of these stages, Green Park Road will be closed to through traffic with local access only from 5 p.m. to 7 a.m.,” Payken wrote. “Otherwise, each stage will be closed to traffic … All residents, except those who reside on Green Park Road, are urged to seek alternate routes …”
