bridge names (e.g. Sihe Bridge) are also getting a name change at the same time. The project was somewhat Herculean since 441 signs were to be replaced. Of those, exit and entrance signs formed 202 signs; other, mainly larger-sized signs, formed the remaining 239 signs. Earlier in the summer of 2004, similar measures for the 5th Ring Road (which had an absent-to-chaotic exit numbering system) were announced. In a show of speed, within the first 100 hours, new exit numberings were put up for almost all of the western stretch of the 4th Ring Road (despite new/old signs being alternated on a different stretch of the ring road). Reaction to the new signs are mixed. There is a definitive plus side: the exits are now matched with their equivalent exit/bridge names on the 3rd and 5th ring roads. Unfortunately, many complain of an information overkill. Signs are now complex enough to hold five different directions (on some bridges). Meanwhile, the mixing of lowercase and uppercase English in small font sizes is another concern. On both the 4th Ring Road and the 5th Ring Road, some speed cameras were put into place, along with the general sign changes.
