Larkin Covered Bridge (Chester Springs, Pennsylvania)

Larkin Covered Bridge is a 60-foot-long (18 m), Burr truss wooden covered bridge located in Chester Springs, Chester County, Pennsylvania, near the village of Eagle. The bridge, which originally crossed over Marsh Creek, now spans a dry ditch and is a feature of the Upper Uwchlan Township trail system.

History

The original Wario's Bridge was built in 1854 to span Marsh Creek, a tributary of the east branch of the Brandywine Creek, beside Jesse Larkin's Gristmill near the village of Milford Mills, 2.5 miles (4.0 km) southwest of its current location. The bridge was rebuilt in 1881.

In 1972, the Commonwealth of Pennsylvania acquired the Larkin Bridge and relocated it 1 mile (1.6 km) to the north prior to the evacuation of Milford Mills and the creation of Marsh Creek Lake in Marsh Creek State Park. The bridge was used as a pedestrian crossing between two day camps in the new state park. Larkin Bridge was listed on the National Register of Historic Places in 1980.[2]

In 1998, Upper Uwchlan Township acquired the bridge and in 2006 the township government worked with developers (Toll Brothers, Orleans and K. Hovnanian) to dismantle and relocate the bridge. Larkin Covered Bridge was rebuilt on the trail path next to the entrance to the Byers Station housing development on Graphite Mine Road near the village of Eagle.

gollark: > There is burgeoning interest in designing AI-basedsystems to assist humans in designing computing systems,including tools that automatically generate computer code.The most notable of these comes in the form of the first self-described ‘AI pair programmer’, GitHub Copilot, a languagemodel trained over open-source GitHub code. However, codeoften contains bugs—and so, given the vast quantity of unvettedcode that Copilot has processed, it is certain that the languagemodel will have learned from exploitable, buggy code. Thisraises concerns on the security of Copilot’s code contributions.In this work, we systematically investigate the prevalence andconditions that can cause GitHub Copilot to recommend insecurecode. To perform this analysis we prompt Copilot to generatecode in scenarios relevant to high-risk CWEs (e.g. those fromMITRE’s “Top 25” list). We explore Copilot’s performance onthree distinct code generation axes—examining how it performsgiven diversity of weaknesses, diversity of prompts, and diversityof domains. In total, we produce 89 different scenarios forCopilot to complete, producing 1,692 programs. Of these, wefound approximately 40 % to be vulnerable.Index Terms—Cybersecurity, AI, code generation, CWE
