Union Pacific Railroad has removed a potential snag to plans to build a skywalk to the new library in Cedar Rapids, Iowa.
The railroad has assured the city that a clearance requirement won't be an issue.
The skywalk goes over some railroad tracks that were renovated earlier this year and raised 6 inches. That puts the bottom of the skywalk into a 25-foot clearance distance required by the railroad by 4 inches.
Union Pacific spokesman Mark Davis says the company reviewed the design and concluded the $500,000 skywalk was in compliance. That means the skywalk won't need to be redesigned, which would have meant additional costs and a possible delay.
