Hi
That does provide extra layer 3 ports and does support bridging

Summary
The Cisco Fast Ethernet HWICs are singlewide interface cards, available as a 1-port HWIC (HWIC-1FE) and as a 2-port HWIC (HWIC-2FE), that provide Cisco modular and integrated services routers with additional Layer 3 routed ports.
Specifications
Feature Highlights
The Fast Ethernet routed ports on the HWICs have the same characteristics and features as the onboard LAN interfaces for the integrated-services-router platforms. Along with Layer 3 connectivity, such as per-port access control lists (ACLs), routing, and IP addressing, these HWICs provide functions equivalent to those of onboard Fast Ethernet routed ports. The following is a partial list of features supported in Cisco IOS® Software for the Fast Ethernet HWICs.
