Construction crews work on leveling a railroad crossing Tuesday at Cato Springs Road in Fayetteville. The work will make it a smoother crossing for low clearance cars that sometimes scrape bottom at the crossing. The work has Cato Springs Road closed between Garland and Vale avenues through Nov. 21. Railroad crossing improvements are part of a larger project to add curb and gutter, sidewalks and drainage pipes along Cato Springs Road between South School Avenue and Razorback Road.
