The first bridge was built by the Prince Edward Island Railway to complete a rail line from Charlottetown to Murray River.
Like the PEIR, it was owned by the Government of Canada and it was upgrading its mainline through northeastern New Brunswick to handle heavier locomotives and rail cars.
These spans were considered surplus after their heavier replacements were installed, thus the federal government decided to salvage the structure for use on the PEIR's line to Murray Harbour.
Before installing the structure, the PEIR hauled thousands of rail car loads of soil excavated alongside the railway line east of the St. Dunstan's University campus several miles northwest of the bridge abutment.
These railcars were pushed in 10-15 car trains to the waterfront and used to in-fill large areas for expanded rail yards and wharves, as well as to build an approach causeway from the Charlottetown side.
The bridge opened in 1905 and immediately revolutionized travel in southeastern Prince Edward Island, allowing narrow gauge passenger and freight trains to operate between Charlottetown and Murray Harbour, as well as pedestrians and horse-drawn carriages and sleighs (and later automobiles) to use the bridge when trains were not crossing; for this purpose, wood planks were placed between and on each side of the rails.
No longer used for rail traffic, CNR wished to rid itself of operating the bridge and tried to get the provincial government to take ownership.
As part of this national project, an improved crossing of the Hillsborough River was deemed necessary, however it required several years of negotiation over joint federal and provincial funding before construction could begin.
Part of the agreement negotiated with the Government of Prince Edward Island provided for a federal-provincial cost-sharing to have Strait Crossing Joint Venture take ownership of and expand the Hillsborough River Bridge from 2 lanes to 4.
This expansion had been studied since the late 1970s when traffic delays began to occur as residential development took place in areas east of Charlottetown, namely the communities of Bunbury, Southport, Kinlock, Keppoch and Cross Roads, creating changes in commuting patterns.
Additional work was undertaken by the provincial government on the approach routes to the span, with additional infilling of Charlottetown Harbour to extend Water Street through the former railway yard (CN Rail abandoned rail service in PEI on December 31, 1989) and intersection with Grafton Street and Riverside Drive.
