The Cortland Street Bridge in Chicago is completed, the first modern fixed trunnion bascule bridge in America, starting the trunnion era in bascule bridge design.

From this date to the present day, the majority of bascule bridges constructed were either trunnion bascules or rolling lift bascules.
What are the changes in bridge construction?
Major changes are taking place at this time. Pin connections in metal trusses are rapidly being replaced by riveted connections, which until this time were uncommon in bridge construction. Steel has replaced wrought iron as the material used in most metal bridges. At this same time, concrete begins to emerge as an alternative to metal bridges, and the experimental period in concrete begins to wind down with an adoption of simple reinforcing rods (rebar) as the preferred reinforcing type. Good Roads movements and frustration with bridge construction quality results in the first state highway departments being formed. These state departments develop standards for bridge design and the role that bridge companies played in bridge design, particularly for small bridges, rapidly declines.

What was the bridge that was built before the National Road?
Before the National Road was constructed, there was already a bridge at the crossing of Dunlap’s Creek. Constructed of timber, this bridge was washed away in a flood in 1808. Hired to design a replacement for the timber bridge, James Finley, a pioneer in the building of suspension bridges, proposed a bridge that was supported by wrought iron chains. Although Finley would go on to design many successful suspension bridges, his bridge in Brownsville would only last until 1820, when the bridge gave way under a team of six horses during a snowstorm. The driver and four of the horses survived the crash; two of the horses perished. After the collapse, another timber bridge was erected to span the gap. Although this bridge would not fail structurally, by 1832, the road surface and condition of the bridge caused alarm.
What is the significance of Dunlap's Creek Bridge?
Dunlap’s Creek Bridge was a major thoroughfare for many years, and passersby marveled at the bridge.

When the downtown area ran out of land, the town began to build up against and above the creek, obscuring the bridge from public view. The addition of new sidewalks further hid the bridge. Although the bridge was not easily viewed, the bridge was nominated for the National Registry of Historical Places in 1977. The American Society of Civil Engineers bestowed a similar recognition. In 1923, a local branch of the Daughters of the American Revolution attached a plaque to the bridge railing commemorating the bridge’s significance.
