Sample Bridge Road crossing reopens after more than a year Updated May 14, 2021; Facebook Share The Sample Bridge, the crossing over the Conodoguinet Creek from the north to the south in Silver Spring Township has reopened after over a year of construction. Construction on the new Sample Bridge started in April of 2020, at a cost of $4.1 million. The previous structure was built in 1957 and was in poor structural condition. “This new bridge provides a safe venue for residents traversing to the north and south of Silver Spring Township, improves our emergency responders ability to serve the community, and allows residents to safely bike or walk with the installation of a pedestrian sidewalk,” said Cumberland County Planning Director Kirk Stoner. “This replacement is one of many county-owned bridges that are being replaced due to age and wear.”
