“…Although FRP bridges are becoming more prevalent, they are on average equal, if not more expensive, based on their initial manufacturing and construction costs. Life-cycle costs such as minimal maintenance, durability, and rapid installation tend to be features that justify use of FRP infrastructure [24,28]. However, widespread use has been restricted; this is largely attributed to a lack of knowledge and experience with the use of this material within the civil engineering industry [45,53].…”

“…Fiber-reinforced polymers can outperform concrete and steel because of their dimensional stability, high strength and light weight properties. Case studies show the average FRP bridge is half the weight of a steel bridge with the same strength and is five times lighter than its concrete equivalent [22][23][24]. Additional benefits of a lighter structure are reductions in energy and construction costs (i.e., transportation, erection, supporting foundations, construction time).…”

“…Depending on the properties of the resins and fibers used within FRP structures, they can be fire and ultra-violet (UV) resistant, electromagnetically transparent, impact resistant, have low thermal conductivity, provide no electrical conductivity, and have low maintenance costs [15,16,23]. They are highly durable, have a life span up to 100 years, and require little to no maintenance for their entire life cycle; allowing FRP structures to pay for themselves over time [24][25][26][27][28]. At the end of the bridge's service life, several technologies for recycling and applications for reuse are available [29].…”

“…The maximum capabilities of this innovative material are not fully understood and require additional research [22]. FRPs support modular construction design, variation in the way the fibers are laid out, and different methods of fabrication [18,24,27,30]. The dimensional constraints of FRP products are limited by transportation logistics, not in the structural properties and technology itself.…”

The proven effectiveness of highway crossing infrastructure to mitigate wildlife-vehicle collisions with large animals has made it a preferred method for increasing motorist and animal safety along road networks around the world. The crossing structures also provide safe passage for small-and medium-sized wildlife. Current methods to build these structures use concrete and steel, which often result in high costs due to the long duration of construction and the heavy machinery required to assemble the materials. Recently, engineers and architects are finding new applications of fiber-reinforced polymer (FRP) composites, due to their high strength-to-weight ratio and low life-cycle costs. This material is better suited to withstand environmental elements and the static and dynamic loads required of wildlife infrastructure. Although carbon and glass fibers along with new synthetic resins are most commonly used, current research suggests an increasing incorporation and use of bio-based and recycled materials. Since FRP bridges are corrosion resistant and hold their structural properties over time, owners of the bridge can benefit by reducing costly and time-consuming maintenance over its lifetime. Adapting FRP bridges for use as wildlife crossing structures can contribute to the long-term goals of improving motorist and passenger safety, conserving wildlife and increasing cost efficiency, while at the same time reducing plastics in landfills.Sustainability 2020, 12, 1557 2 of 15 connectivity for particular species [8]. Although usually more expensive than underpasses [3], overpasses are also frequently chosen by some species [9].The length and the width of overpasses continue to challenge engineers, architects and ecologists. Some overpasses are required to span six or more lanes, including Canada Highway 1 in Yoho National Park and Interstate Highway 90 in the Cascade Mountains of Washington. Some newer designs are anticipated to exceed lengths spanning 10-12 lanes. The proposed wildlife overpass on Highway 101 in Liberty Canyon, California, will require bridge spans up to 60 meters (m) and be the largest wildlife overpass ever built, as seen in Figure 1 [10]. Common widths of overpasses have been designed from 30 to 60 m and even wider. These geometry requirements can result in massive and relatively uneconomical structures. Many existing wildlife overpass structures are constructed to support heavy loads that incorporate excessive backfill to host native habitats, such as forests. This design feature adds substantial weight to the static and environmental loads the structure is required to support. Supporting these loads over multi-lane roadways further results in relatively high costs compared to underpasses or other less-effective mitigation measures. Because of the costs, the siting of these structures is especially challenging as they can only be provided sparingly across a large area where WVCs commonly create safety issues for drivers.

The paper presents the smart FRP composite bridge panel called „OptiDeck“ with integrated distributed fibre optic sensors (DFOS), to monitor the panel's behavior. The panel is intended for use in newly build and refurbished road bridges. From structure point of view the uniqueness of the presented solution results from innovative technological production process to create a honeycomb core in thick sandwich panel. In order for the monitoring system to cover the entire surface of the panel and to detect local damage, it was necessary to use a modern solution based on geometrically continuous DFOS system. The DFOS system serves as the structure health monitoring (SHM) system, which has been tested during the production and laboratory testing of a prototypes in natural scale. The advantages of DFOS measurements are well known and applied in many civil engineering applications. However, the potential benefits are still not fully utilized. Finally the experimental verification of the DFOS system integrated with the FRP deck panel is presented.
