re: #358 Russkilitlover
Or, conversely, we refer to them by name - The Golden State Freeway, The Pasadena Freeway, The Harbor Freeway, the Long Beach Freeway….etc. REALLY messes with the tourists!
We use the names a lot here. Even the traffic reports use the names instead of the numbers (with the exceptions of I-80 and I-57 which lack names).
