1. Live GIS data
Not loaded yet.
Data is read live from the state GIS services each time this page opens, so results always reflect the current records. Loading takes about 10–30 seconds.
2. iTAP verification file (CSV)
No iTAP file loaded.
The Select/Non-Select layers don't record demolitions, so the iTAP result for each bridge is kept in a CSV you maintain in Excel.
Download iTAP worksheet gives you every INDOT bridge with what SHAARD currently says, plus any iTAP entries already loaded.
Fill in the iTAP Status column (Demolished or Standing; iTAP's own Nonextant / Extant wording also works), save as CSV, and load it back here. You can also load iTAP's Search Results export (.xlsx) directly, no conversion needed.
Only the NBI, iTAP Status, Checked On, Checked By and Note columns are read; other columns are ignored.
