Commercial Pedestrian Bridges – Factors That Affect Their Cost

Aug 30, 2023 | Blog

As a contractor, when planning to commercially make a pedestrian bridge connecting parks or bustling community spaces, you must have thought about some behind-the-scenes factors that influence their cost. This blog has detailed this information, aiming to answer all your queries.

Factors That Influence Pedestrian Bridge Cost

The costing plan serves as a foundation when starting to build a commercial pedestrian bridge. The number is not absolute; it fluctuates on the basis of factors such as size, choice of material, the bridge’s eventual home, etc. Let’s break down the cost factors that shape the bridge’s financial outlook.

  • Material Costs

The heart of any bridge lies in its construction material, and this choice significantly influences expenses. The material factor ripples across various aspects, including upfront investment, transportation, ongoing maintenance, and potential repairs. Here’s a comparative look at three common materials: fiber-reinforced polymer (FRP), wood, and steel bridges.

Fiber Reinforced Polymer (FRP)

FRP is a lightweight and durable material that strongly withstands nature’s wrath. While its initial cost might seem slightly higher, you save a good amount in the long run. Typically, expect the price to range between $600 – $1200/linear foot, and for an FRP stringer/beam bridge, its $350 – $650/linear foot.


It is conventional and the most cost-effective option. A wood truss bridge is low on initial investment and high on yield. However, they do need a hefty capital set aside as maintenance costs in the long run. Usually, a wood beam bridge (of 6ft width) ranges between $300 – $400/linear foot.


Steel bridges have hefty transportation expenses solely because of their weight. A steel truss bridge, on average, can fall between $500 – $2,000/linear foot; on the other hand, a steel beam bridge is estimated within $400 – $1,600/linear foot.

  • Construction Costs

While planning the budget, do not only focus on material expenses. You must also factor in transportation and labor, as material savings can sometimes mean higher construction costs. Here’s how the construction process affects:


It is a cost-effective option since its prefabricated parts and ease of assembly reduce construction charges. FRP parts are easy to transport, and construction can be done using hand tools.


Although wood, with its low density, is cheaper and easy to transport, its weaker strength can increase costs. Skilled labor and special machinery might be required for assembly, impacting the budget.


Heavier steel parts ultimately mean increased transportation expenses. The main contributor to the cost is full or partial assembly before on-site delivery. Experienced and efficient labor, along with heavy machinery, are essential for steel bridge assembly.

  • Operational and Maintenance Costs

You might think that bridge costing is only related to the building; however, the truth is that it is all about long-term upkeep. The material you choose today will impact labor, repairs, and eventual replacements.


This material shows an impressive lifespan of over 100 years with less maintenance, thanks to its UV and corrosion-resistant characteristics.


Wooden bridges can last anywhere between 25-50 years; however, requires frequent maintenance throughout their lives.


Although it has a century-long lifespan, steel bridges need regular maintenance to endure changing environments.
