This is due to Road Construction on First Avenue this summer. Should be rebuilt by the end of the summer at the latest. Large Cracks between lanes parallel to flow. These will grab a wheel and put you down hard. City has no jurisdiction over State roads.
Stoplights are unresponsive to bikes.
Let us know if they are still a problem. Iowa City Whiting Avenue Ct. Could hurt car axele, bike tire, pedestrian tripping. I ride this every day and it is dangerous for bikers, especially since cars go whizzing by. The mechanism that changes the light is not sensitive to ba bicycle.
