CON/SPAN O-Series Serve as Land Bridges at New Park
Two sets of twin cell CON/SPAN® O-Series® Bridge Systems serve as "land bridges" that connect Tulsa's new 66.5-acre park. This precast option was selected over cast-in-place for its cost savings, speed of installation and quality control. After the units were installed via crane, the bridges were covered with up to 14 feet of fill, as well as trees, landscaping and park structures. Each CON/SPAN cell is wide enough to accommodate two lanes of traffic.
Corrugated Metal Pipe and a CDS hydrodynamic separator were utilized at Renaissance Pebble, a 24-hour assisted living community, to pretreat, manage and retain stormwater runoff.
After a large storm event caused critical failure to the first 40’ of an existing culvert, DuroMaxx® SRPEliner pipe was used to reline the entire length of the 326' long structure. DuroMaxx was ideal for this solution because it adhered to AASHTO and ASTM material specifications and featured proven joints.
ArmorFlex® Articulating Concrete blocks were utilized to minimize the potential of erosion downstream of the new spillway. This product was selected for its reliability and speed of construction.
Part 3 - Attention to Structure Type, Shape and Size Selection
This article is the third part in a blog article series focused on the basic fundamentals related to selecting material type, structure type, structure shape and size selection for culverts and buried bridge structures. In this third blog article in the series, thefocuswill be onarch shapes and footings, including attention on required site soil bearing strength. As with the previous articles, the primary focus here will be on corrugated metal and structural plate offerings.
Street trees provide multiple benefits in our efforts to address stormwater quantity and quality. Like all other things, there can be issues associated with these benefits, especially in the urban environment. In this blog post we take a look at these issues to make sure they are part of the design and management process.
