Custom Backyard Bridge Over a Creek in Phoenixville, PA
When a creek cut this Phoenixville, PA backyard off from the rear acreage, Sunny Ridge Construction built a pressure-treated wood footbridge sturdy enough for a riding mower, anchored on four concrete-filled sonotube footings, with a gentle rise and fall that keeps it wheelchair-accessible.
The Challenge: Getting a Mower Across a Backyard Creek
The property continues well past a small creek, but there was no safe way to get a riding mower, or wheels of any kind, across it. A decorative garden bridge would not do: this crossing had to be capable of carrying real rolling weight, sit stable through wet seasons, and stay gentle enough to roll over.
What We Built: A Mower-Rated Wood Footbridge
We set one sonotube at each of the bridge's four corners, each 12 inches in diameter and 36 inches deep, and filled each carefully with concrete for long-term stability. The finished span runs 16 feet long by 5 feet wide, crossing the creek with roughly a 15-degree rise and fall, easy for the riding mower and wheelchair-accessible as needed. We chose pressure-treated lumber over a composite decking since the homeowner wanted the wood to weather and grey naturally rather than the look of a vinyl composite. Picket balusters, sometimes called spindles, line both sides under a smooth continuous handrail.
The Result: Reliable Creek Access for Mower and Wheelchair
The homeowner can now run the riding mower straight over the creek and maintain the rear acreage without a detour, and the crossing works for wheelchairs and foot traffic alike. The homeowner, Kevin Rooker, left a 5-star Google review describing a bridge "anchored with cement" and "sturdy for myself to cross as well as riding mowers," and called the crew "polite, tidy, and efficient."

Optional Upgrades to Consider for a Backyard Bridge
Low-voltage post-cap or rail lighting makes the crossing usable after dark. A penetrating stain or sealer schedule extends the life of pressure-treated decking in a damp streambed, though this homeowner chose to skip it and let the wood grey naturally. We would skip oversized structural add-ons; four concrete footings already carry more than foot and mower traffic requires.
Backyard Bridge FAQs
How much does a backyard bridge cost?
It depends on span, foundation, and materials. A pressure-treated crossing like this one, a 16-foot span at 5 feet wide on four concrete footings, runs roughly $3,000 to $5,000.
Will a wood bridge hold a riding mower?
Built right, yes. This bridge rests on four concrete-filled sonotube footings, each 12 inches wide and 36 inches deep, sized for rolling weight rather than just foot traffic.
Can a backyard bridge be wheelchair accessible?
Slope is the key. This bridge rises and falls at roughly 15 degrees so wheels can cross without a step, which the homeowner confirmed meets their accessibility needs.
What keeps a bridge from shifting over time?
The footings. Deep concrete-filled sonotubes hold each corner stable through seasonal ground movement and wet weather, so the span stays true.
Do I need a permit for a backyard bridge?
It varies by township in Chester County. No permit was required for this bridge.
