Getting around: Zhongshan Park construction and Lujiazui rerouted

In the local press recently:

• By year's end, the Zhongshan Park Line 2/3/4 interchange station's single intra-station passageway between the Line 2 and Line 3/4 platforms will be joined by a new passageway added to relieve passenger congestion. Since the opening of the Line 2 extension, passenger traffic on Lines 2 and 3 has been grown markedly and the pedestrian traffic during rush hours is almost unbearable. The new passageway will be located on the south side of the station, running past the bookstore and convenience store. The current passageway at that spot is a station exit, but also branches off into a tunnel under Kaixuan Rd to the Line 3/4 station entrance. Has anyone seen evidence of construction going on there?
• Seventeen bus lines that stop at Lujiazui are being rerouted due to construction in the area. The 17 lines will be distributed between the Shanghai Aquarium, the bus stop near the Pearl Tower, and across the traffic circle at the corner of Lujiazui Rd and Fenghe Rd. The article mentions that related government officials predict a decrease in the number of passengers switching between the Metro and bus systems at Lujiazui after the move; perhaps this is serving the dual-purpose of also being a stop-gap move to shift passengers from overloaded the Lujiazui station to the Dongchang Rd station. It's also possible that the construction in the article is related to the oft rumored project of connecting several of Lujiazui's office towers with downtown-Hong-Kong-style above-street-level walkways.
