1 Introduction

Associated Engineering (AE) was retained by the City of Vancouverto complete the retrofit and

strengthening scheme for the concrete approach spans to allow the bridge to safely carry CSA-

S6 CL625 vehicle loading.

2 Existing Girders of Concrete Approach Spans

The Burrard Street Bridge, shown in Figure 1-1, consists of steel truss main spans and concrete

approach spans.
