Reader Heidi Hagen’s photos of construction on the North Line along N. Main St. north of UH-Downtown show the new bridge that’s “popped up outta nowhere” around Hogan St. No, there’s no rainbow at the north end of Downtown, but if you look carefully from the right far vantage point can see the elevated concrete and steel construction that’ll be carrying an extension to the existing rail line over the Union Pacific railroad tracks to further points north: Lindale Park, the Northline Transit Center, and 6 other newly named stations.
